I ran at 32:1 for 20 years, same piston, same main bearings. You have to make the decision if the nano second in engine response is worth changing bearings/pistons if you run at 80:1.
Get any reputable brand, fairly tight and stick some plastic shin / knee protectors down the inside. In my opinion, if it isnt hard plastic it wont really do anything.
that is almost as much as a stupid idea as changing from a 4 stroke to a 2 stroke then back to a 4 stroke during a multi day event and hoping no one notices......
This is my 5TA in a heavily modified B40 frame that I shortened and tightened up the steering head angle. I originally bought it off a mate as an unfinished project 24years ago. I lowered the compression, dropped the primary and secondary gearing and fitted an electrex ignition system, apart from that the motor is standard.
I have since given it 2 facelifts, the last one included nickle plating the frame and anodising the rims and parts dark green, probably not popular with the purists!
As for the 350 or 500 debate, although people say that the 350 is smoother, the 500 is so much fun and will pick the front up anywhere in any gear. Even after owning it for so long I still look forward to riding it, and wouldn't swop it for the world [/img]
Most of that is very nice (purist) How does it grip ? Whats are the tank and forks ? Really like the nickel frame, ball park cost and who did it please.
Along with all the other mods, I now reckon I might need to raise the gearing a little. I currently have a 60 tooth rear sprocket. I was thinking 56 might be better?
As the sprocket is aluminium I was thinking if I got the dremmel in and ground one tooth off every 90 degrees that will do the trick ?
The down side is that if i need to go even higher i will have to grind off 4 more teeth (to keep everything balanced like)which might be too much , so would it be be better to start by grinding off one tooth every 120 degrees and then if i need too I could remove another 3 ?
Easy way to raise the gearing is to get longer shocks.
