    The one on the 89 bike did not line up correctly either, had to adjust rear bracket on expansion pipe to obtain correct alignment, otherwise silencer disappeared under rear mudguard and connection to cylinder twisted

        rebuilt the carb last night still not rebuilt to perfection far from it some screws were f!cked I replaced what I could il need to get some new ones ideally but the screws I put back on are good there was no gasket for the front of the carb and mine is knackered its sitting ok though ill replace when I do it fully with new screws etc the rebuild kit came with a different needle to the original I eyed them up and the highest setting was equal to the second from bottom that mine was on taper was different to couldn't see the main jet size I had 210 and 225 I put 210 in its now fitted and seems to be running fine might be a bit lean but its reving cleanly all the way through so it seems anyway gonna take it for a run later and see what the plug tells me and if my problem at high revs has been solved

          @terry-tz you'll want atleast a 230-240 main with Romeu pipe mate, I run a 250, but have snorkel removed from airbox.

                @terry-tz was that wide open throttle ? Looks a tad rich to me.

                  @calum bare in mind its a used plug pretty new though and was in a bit ricker state mainly wide open hangs I tad in the middle think I might be a tad rich on the needle or the taper's not that great

                    I would rather err on the side of tad rich than lean lol.

                      any suggestions I'm still having problems with what I thought was full throttle when I'm in 5 gear it bogs seems to be any throttle now before I cleaned the carb it was funny in all gears and 3/4 plus throttle I no there very different symptoms but I'm very sure its the same problem

                              @glynn123 Funny, my DEP was sound on 210 main. It was actually when I fitted a Wøssner Piston did I find jetting an issue, think I needed 280 main in the end to get the jetting sorted. It should be done a bike per bike basis ideally.

                                    @terry-tz I can't say I noticed a change when I upjetted it, it was purely to get it to not bog out.

                                    Bit difference with a DEP pipe though.

                                      @calum that's weird, I'm running a wossner piston with 250 main, but I suppose you run open filter rather than airbox don't you?

                                          @glynn123 This was way back when. I may have ran the 3MBP barrel. But whatever it was, I was having difficulty getting the jetting spot on.
