bradgg125 Posted April 20, 2008 Report Share Posted April 20, 2008 When i flip the back wheel round while going down a hill my bike cuts out. is this normal? ( i presume not) and what can i do to stop it apart from reing it at the same time? Quote Link to comment Share on other sites More sharing options...
bob Posted April 21, 2008 Report Share Posted April 21, 2008 I presume you are talking about the bike cutting out when it is at extreme downhill angles? Have you done the proper float height setup as described on R2WTrials' website? I had the same problem on my previous two bikes, but the carb setup sorted it, it is probably just the bike flooding. Also worth trying may be the carb extensions available from beta dealers if you have running problems after doing the mod. Tinkering is the best policy.

eddie_lejeune Posted April 24, 2008 Report Share Posted April 24, 2008 If it is the new bike then you havent the float height set correctly, if its the mikuni i dont know Quote Link to comment Share on other sites More sharing options...
bob Posted April 25, 2008 Report Share Posted April 25, 2008 Sorry, forgot about that, the new carb has a different float setup to the previous, there are recommended settings for both if you look about these forums. Bob Quote Link to comment Share on other sites More sharing options...
madcr500 Posted April 25, 2008 Report Share Posted April 25, 2008 When i first got my 97 scorpa it used to cut out going steeply uphill down hill or leaning it over. I dropped the float height by 2mm and its been fine ever since (except when my choke was sticking slightly) Quote Link to comment Share on other sites More sharing options...
putrid_fruit Posted April 30, 2008 Report Share Posted April 30, 2008 Yes it's normal... No it's not supposed to happen. The drilling mod that is in these forums and here: http://www.kdmototrials.com.au/Tech_MIKUNIFix1.pdf addresses this specific issue. The float height is related but mostly about idle/ low revs quality. It's free (no cost) to set correctly. The float extension is for the opposite problem to what you have, its for extended up hills so that the bowl has a bit more volume and picks up lower (meaning it can still draw fuel at a sharper incline. Before you do the drilling mod ensure that your breathers/ overflow are free and that the one on the exhaust side hasn't melted and pinched off. So if you do the float height and check your breather/ overflows are clear I would be very surprised if you needed the drilling mod, but if you do, thats what its for. It essentially raises the level at which the overflows start to bleed, which on the extreme nosewheely angle is too low, as from the factory. Cheers, Chris.
