I think I've got...!!

I sent the forks off for a total rebuild today so I figure in a
couple of week I'll have that back together again.
I found a complete front wheel assembly for $100 and twelve
hours of cleaning.

Then I'm into the engine work...carb sliders are stuck, clutch is stuck, right exhaust spigot is loose....maybe broke...maybe stripped...and that's just what I've figured out while
cleaning on it....the engine kicks over and feels right so I hope that the exhaust spigot is the worst of it....

Wish me luck....

Great to see your bike looking better & better in each pic Skitch. I have the Tiger version of your bike so it's great to compare notes. Two things I noticed are the OIF filler cap which looks non-genuine and your forks.
Did the Bonnevilles front forks come with a raised polished rib down their outer side like the OIF Tigers? (see pic)

Nice work though and it will be great to see pics of its progress?

great bike skitch, i had the same and i can tellyou!!
be patient and youll be rewarded.ask question even the more futile(there is no futile question in fact) we'll be happy to answer!!!
you have a 71 trump and you must be very very soft with the one year only valve clearance adjustment caps as these pretty little things are very fragile especially the thread which are made of hardened marshmallow......DONT OVER TIGHTEN THEM !!!!!! or you'll be in trouble :hammer: :hammer: :hammer:
otherwise it's anice and quite straightforward restauration project.maybe new amals if yours are too worn out

Hi Grand Prix 125, is far as I know the non ribbed forks are original but I do like the ribbed version alot. The Bates hi Rise bars were installed by the dealer in 73

I'm the first one to do this much work on this bike since it was new....my Uncle bought it new and it only has 13,000 miles on it.

I don't think I'll have to pull the engine out of the frame but if I do I'll be working towards getting it as nice as yours..that's really a nice job GP 125.

Gotta go to work.

That bike looks great, I wonder what happened to the front wheel? It sure looks out of place.

Do not use modern bike cleaners on the original paint or it will be a sad ending.

One "modern cleaner" you can use is Lemon Pledge. Safe and cleans well, leaves a protective coating.
Leave the valve adjuster access ports on the side of the rocker boxes alone. You can't accurately adjust the valves of a used engine with feeler guages, anyway, so just don't mess with them, and you won't strip them. If they're leaking, remove them....carefully....clean, and reinstall with locktight. Then just forget about them.
John Healy at Coventry Spares used to make an alloy replacement which was far better, but I imagine the market dried up pretty quickly for that item.

Oh, and the exhaust spigot? Clean the adaptor and the head, squeeze in some silicone RTV and thread the adaptor back in. Remove the excess and allow to cure for a couple of days. Reinstall the exhaust with ALL the brackets. You may have to shim or bend and fiddle with the front L brackets to get an easy fit, but it's worth the hassle. Nope, you don't even need to use "high temp" RTV.....the regular cheapo bathtub seal works just fine.
When you reinstall your bars, be aware that the rubber mounting parts are very specific and need to be installed in order and the right way around....in particular, the top washer must be fitted with the flat side up and the tapered side down, against the rubber. There is a relief cut into the washer that keeps from pointloading the junction on the P clamp to keep it from fracturing. THAT would be exciting.

lower fork sliders on 71's had the ridge and a natural cast finish. '72's had the ridge removed(except by the drain screw area) and a polished finish.

Thanks for that info on '71 models Kadutz.
Do you happen to know what the original finish of the conical hubs and front brake air scoop was?
It seems every '71-'72 Tiger/Bonneville you see has either a painted, highly buffed, chromed or natural finish. I feel they may have been a polished and lacquered finish that discoloured over time but I wasn't into Triumphs when they first came out in the show rooms.

PS sorry for hi-jacking your thread on this question Skitch, I should have started a new topic. :wink:
