98bonerSTOCKshee Posted October 5, 2004 Report Share Posted October 5, 2004 ok I finally took the stock head off, the head is fairly clean with only a few smudges. Cylinders are clean and groove free, no ridge at the top either. The pistons have some carbon build up on top, looks like it will easily wipe off. However I can wiggle both of them front to back and side to side. The question is how much is ok? This motor has never been torn into and it's the original '98. I had great compression before removing the head. The new domes are only 21cc. If money is advailable should I do the top end or wait?

banshdog Posted October 5, 2004 Report Share Posted October 5, 2004 If you had good compression before..... I would say put the new head on and test compression again. Unless you want spend the cheese on a new top end, then go for it while the head is already off. Quote Link to comment Share on other sites More sharing options...
Toomey Banshee Posted October 5, 2004 Report Share Posted October 5, 2004 I would guess, if you are on the stock top end, and you still have good compression, with the cool head and the smaller domes and increase in compression your top end will last a season. I would just do the top end now and get it over with. Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted October 5, 2004 Report Share Posted October 5, 2004 I think you will find the head is easy to intall and remove, the annoying part is draining all your coolant especialy if you use teh expensive stuff, and removing and installing plastics. What was yoru compression before you put the head on, and were there any mods to the stock head? Quote Link to comment Share on other sites More sharing options...

This motor has never had a bolt broken loose on it, except when I added the water pump.. I have decided to freshen up the top end.. It can only get better.
