        @DTR-NSR that’s what I was going for that old dull gold not the best but everything I’ve done is better than it was and it’s now a semi respectable bike that isn’t rusty or broken everywhere you look

              I wasn't happy with the way the bike turned out the black engine turned hideous when fuel touched it and the gold frame was just a bit too much so now the frame is satin black as are the rims and I've been working on the engine it's not finished yet but I'm happy with the over all look, it needed mains and seals so it seemed the perfect time to paint it up also have a stainless bolt kit coming for the engine. It does need new rings but I'll get them at a later date, also got v force reeds on there

                  @declan I quite like the blue barrel and head. Can I pick your brains on the wheels please? I plan on doing my wheels satin black. Have you got any tips for Which primer to help the paint adhere to the standard (chrome?) Rims please? Also which paint and lacquer please? I've considered powder coating but I believe I'd have to strip and rebuild the wheels

                      @markus-w I can't help you out too much bud the wheels were just a quick and dirty job, originally I sprayed my rims Matt black no primer no lacquer and it adhered almost perfect to them I went over that with a gold brush on paint rustoleum I think it was and that adheres to anything then I just brushed satin black over that I intend on doing them properly at some point, if I were doing it without powder coating I would use a self etching primer cover the chrome fully them just pick a good quality paint of your choice and do light coats one 500ml can should be enough for both wheels providing you do light costs I personally wouldn't bother with lacquer but that's your call.

                              hey guys so it was test fire fast today and after a ton of kicking it ran twice for a few secs it was very weak I've narrowed it down to a weak spark the spark is blue but even if I hold the plug it doesent shock me nor if I put my finger in the ht cap the stator was tested as good not too long ago I will have to re check that I can't see anything obvious on the cdi side of things, but my wiring loom is bad a lot of connectors that just don't have anything connected mostly bullet connectors behind the headlight besides the kill switch which I also don't have is there any wires not including the key switch that can ground and weaken spark

                                  @declan I bought one of those "Racing" coils. Nothing but problems. Since fitted genuine 3WM Coil now runs fine.

                                      The bike runs decent but I still have play in the stator side crank even though it has brand new koyo mains is it possible the crank has worn down somehow over the years, it was all tight when I fitted them and it's only ran for around 3 minutes and I have a top end rattle I can't find any cause for this piston fits good no compression change powervalve seems fine it didn't have this sound before the only thing that's channged are new mains new piston and v force reeds it doesent sound like the crank I'm also using a thinner base gasket but surely that's not enough to cause issues?

                                        The play in the flywheel feels the same as it's always been I rode it for years with the same play so I'm assuming the crank surface might have worn down, when it's running and I put my finger on the plastic pv pulley there's a deep sounding impact noise as far as I'm aware it's always done that is that normal?

                                          @declan

                                          Is the piston over 57mm? Sometimes the power valve needs grinding to profile so it doesn’t hit the piston. The same with the head and the head gasket.
                                          Have you adjusted the power valve position and/or gotten a rebore very recently?

                                          The new bearings should eliminate any play. Are you sure the flywheel is tight on the crank? Do you have the thick washer fitted under the nut?
                                          If you undo the nut and the flywheel is anything other than on there tight and needing a puller to remove, there’s something wrong...

                                          I use a large flathead screwdriver to check for main bearing play on the flywheel side. Very gentle up and down pressure shows any real wear. Anything else is just flex in the shaft...
