Well I forgot to order some grips and a new throttle tube on my parts order the other day that arrived this morning so went in my Parts Cache for the Elsies. Total result!

Gonna run the pattern levers for a while got such a bad habit of catching levers haha! Few nice green bolts.... Ahhhhh Green!!

Looking forward to getting stuck in tomorrow and gonna order some tyres so I can get out toward the end of the week itching to go for a ride now especially with this nice weather forecast.

If you are looking at tyres, I think Bridgestones suit the handling of an RD, I'm very happy with them

Thanks Motty not sure if they come in the right size for my narrow 1.60 front rim.

Had quite a long phone conversation with Dunlop Technical about the 1.60 Front rim got a proper understanding of how it all works now Be interesting to see what the other tyre companies reply with.

K82's or me77's are correct size.

Today was one of those days where everything that can go wrong did go wrong haha!

Pattern Parts strike again had issues on my Elsie before so always bought genuine where I could, clutch lever assy was perfect so that's all fitted clutch pull feels alot better now.

Next up was the brake lever shoulder looked totally wrong bolt hole not lining up properly with the perch so stuck the old one back on and ordered a Genuine C one from our very own RDJames through ebay so soon as that baby arrives I'll get that fitted.

Just emailed Yambits so shall see what they say looks like it's a part they have bought in just really irritating.

Moved onto trying the anti vibration rubber that was missing luckily this bit fits lol.

Tomorrows job I'm gonna whip the l/h engine side casing off an just double check the oil I've seen then I'm gonna get back to polishing the wheels an order some tyres in at my local place and put a order in for some more parts once I work out whats still available.

Quite a bit of an improvement looks wise so gonna get the rest ordered an get the cylinders all sprayed up might have a painting day on Thursday and spray a few of the satin bits.

Should the bottom of the master cylinder be gloss or satin on the 250C?

Got stuck in after finding the oil pipe joint issue checking a few other things out.

Missing the split pins under the anti vibration mounts on the bars, ones perished so sorted some new ones of those.

Checked behind the generator cover
Was pretty grubby with old stuff off the chain no signs of oil so that's good :) gave it a bit of a clean up.

Noticed the gear lever had been set to low an had put a groove in the l/h silencer so moved that a few notches.

Tried to get my tyres ordered but realised my tyre guy is on a half day gutter!

Fork seals are good although the dust covers are in the bin so fitting some new dust covers tomorrow. The pitting on the fork leg is well outta the travel area so just gonna turn that round so it's outta sight an then sort them later in the year.

So far so good gonna give it a compression test later cold just to see if the cylinders are reading the same then do it warm once I fix the oil feed.

Who's everyone using for head gaskets now genuine are discontinued? Might give it a de coke.

Anyway back to polishing spokes!!

Bit more progress went round the bike polishing bolts.

An did a bit of work on the rear footrests quite far gone so didn't think they would come up


Other side :)



Finally did a quick compression test on a cold engine after finding the oil elbow loose just wanted to check :) nice and even between both the cylinders.

Few bits coming that I ordered earlier in the week should be here tomorrow so should make some more rapid progress tomorrow!

Coming along nicely mate, i had problems with a few Yambits parts too but they were excellent at exchanging or refunding  me if the parts were faulty or didn"t fit,some parts might be dodgy but customer service is superb in my opinion and don"t forget Fowlers do 10% discount for paid up members but you have to order by phone .

Yep they tagged a extra lever in my order today for me to check out :) if it's not right again can post them both back.
Do agree customer service is good just a shame the stuff isn't right in the first place had enough of making things fit on the Norton's haha!

Really looking forward to getting stuck in again in the morning when stuff comes. Was a shame my tyre guy was shut today as probably won't get them now before the bank holiday epic weather haha will just have to take the rd250lc out for a run when I'm not working on the 250C while the weather's good.

Gonna order some lockwire stuff for the oil line joint tomorrow want peice of mind on that as it's super loose.

Planning next Wednesday to be the first run out really can't wait!

Lots progress the new lever from Yambits was even worse! Haha.

Decided today was a painting day ! The engine was driving me nuts cosmetically so got stuck in on that beauty did the cylinders and side casings best I could with a bit of wind :) also learnt a trick on the edges of the badge on one side so need to repeat that for the r/h side.

Tomorrows job is the front caliper and the brake m/c paint wise, then gonna fit the new dust covers on the forks. All in all feel like she's really coming along now!

Not perfect but the engine paint will see me through to the winter :) as I wanna get out on her soon as!

Green bolts inbound for the engine side casings :)

Well today was one of those super long days!
Stripped the forks of the bike an dad spent pretty much all day getting some scrapes an scratches out of the fork lowers. Decided to check the front caliper put before paint which turned into splitting the caliper halves as the piston had seen far better days so gonna order a piston kit on Tuesday.

Next task was to split the disk from the carrier.. huge nightmare with some of the bolts got them all off though without breaking any, gonna order some of those as well.

While the bike was canted back with the forks of it started leaking gearbox oil outta the crankcase breather. Well up on the dipstick so gonna drop it an put the right stuff in. Wondering as well if it's got the right dipstick in :)

Painted the carrier up was really far gone but she seemed to come back ok.



Also took the rear brake pedal off an painted it just gotta sort the setup out on it again :) any tips greatly appreciated for the position of the plate an spline behind the brake pedal/frame. Probably all make sense when I'm not as tired tomorrow :)

All in all a super productive day not many pictures bar the brake carrier but I'll add some tomorrow when I get stuck in again.

Yep keeping the original frame paint etc just sorting the bits that are properly to far gone :) was driving me nuts having no paint on the carrier haha an a raft of rusty bolts managed to clean a few up so probably gonna try the rest.

Rather be on something tidy than a mess, agree though very fine line an don't wanna over restore it got a LC that's full of nos parts so don't feel the need to chase that on this one an a LC that's just a daily rider.

Glad I spotted the piston on the caliper was to far gone to keep ones seized in solid as well and none operational. Are there any marks on a genuine caliper?

Looks miles better now the dust seals are replaced on the forks ones that were on had electrical tape holding them together. The little touches seem to be going a long way.

Seat cover looks original few tiny tears but keeping that.

All in all the re commissioning is going well I think :) new tyres this week then I can get out on it.

Plan for tomorrow is finish the fork lowers. An go a bit steadier was like a furnace outside today.

An set the rear brake pedal up again. Oh an more spoke cleaning ha!!

Got really stuck in today bit of a late start after braving the food shopping madness!

Finished the brake carrier an tried it on the disk, then spent a while polishing all the rust from the locking tabs and bolt's they came up great :)


IMG_20190420_170755801-01 by norton.rider, on Flickr

Next up got all the deep gouges outta the fork legs lots an lots of polishing to manage it :) Gonna put the correct finish back onto them tomorrow looking really good though. Dust seals are a huge improvement!

IMG_20190420_183820729-02 by norton.rider, on Flickr

Painted the front MC up an fitted the genuine brake lever I got woop went on with no issues.

IMG_20190420_183720904-02 by norton.rider, on Flickr

All in all 8 days in really feel like I've made allot of progress.

Got a set of Metzler ME77's on order so looking forward to getting those fitted on!

Dad did took over on the front wheel polishing while I was doing all the little tasks an he had a mess with the seized in half of the front caliper.

Tomorrow I'm gonna finish the front wheel polishing, finish the fork lowers, an then do the oil union repair on the carb. Finally thinking I'm gonna drop the oil then start checking all the oil pump an carb settings. Not far off the first ride now once the tyres are replaced.

Wow I'm shattered!! Another full on day on the RD250C it's amazing how far its come from the wheels and other components being a corroded mess to the current state in just over a week since getting her on my 30th Birthday. Looking forward to the new tyres and getting out on her few more bits to order and a few more jobs to do this week.

So far rebuilt the forks.
Fixed the 2t oil joint union that was hanging out!
Refinished the engine cases and cylinders.
Replaced the engine anti vibration rubbers.
Removed all the paint from the rear grabrail/subframe.
Endless bolt polishing from rust back to the correct finish.
Fitted new Anti vibration bar rubbers + the missing clips to stop the handle bars falling off!
Compression test A OK!
Lots of cleaning and polishing on her.
Fitted new clutch perch + lever + genuine grips + genuine brake lever after 2 pattern ones didn't fit.
An the bane of my life got the front wheel an rear wheel from a corroded mess to shiny!
Stripped the front brake disk carrier an got all the corrosion off polished the splines and repainted it.
Stripped the front caliper and 1 half is beyond repair.

Hope you are all enjoying the progress.

Tomorrow's plan is going over the oil pump/engine setup new fluids and bleed it all through :)

As the gearbox oil is well overfilled been leaking out the crankcase breather with the bike canted back with the front wheel off or a seals gone on the pump an the 2t tank has emptied itself into the gearbox. gonna drop it tomorrow an find out whats going on.
