yep i agree, it looks like your in the same pile of shit im standing in. just so your aware all the missing nickasil is probally in your crank bearings, so you will at a minimum have to spliit the cases and clean it all out thoroughly, preferably new crank bearings.

no leaking coolant that im aware of, the left cylnder also had it flaking off but only a small amount and up near the top on the intake side. plugs and tops of pistons look like its running sweet, so im a bit confused as to the cause of this issue. what brand domes did you change to? as one of the domes has a fair amount of nickasil hanging out of it, so i have to replace it anyway. the cylinders ,head, domes etc are part of Trinitys complete 421 kit with carbs etc, so what domes will suit this head? thanks guys.

Hi all i have a very new 421 cheetah, it was a complete kit from trinity, but im not sure about the cynlders, as the suplier in Australia had them on the shelf, and his reputation isnt real flash so im not sure on there past. motor was profesionally built, run in , dynoed, and then in its first compeditive race i didnt even finish the first lap. (lap 30 miles long) i got about 28 miles. backed of at the end of the straight and it started dying so i clutched it and pulled over. everything seemed fine so i went to restart and noticed it was low on compression. drove home and stripped it and this is what i found. any ideas on the cause?

where to start. the B8ES plug can create a pulsing type effect back into your bikes eletrical system, hence effecting your CDI etc. they have absolutely nothing to do with your neighbours tv signal. you timing plate WILL NOT give you anymore spark then standard. (only effects spark timing not spark size) a dyna FS WILL effect spark size and timing, so you get the benifits of the timing plate with the added bonus of a cleaner, stronger spark. the iridium plugs WILL help produce a brighter, more agresive spark due to the thinner electrode. + with the dyna FS you can change ignition curves at the flick of a switch depending on the riding your doing. more top end, more midrage, more low down for tight woods etc.

Thanks heaps

Any news on the pipes?

will you post to Australia? if so i need a set of CPI SB inframes as soon as you can get them here. you have a pm
