zts gixx Posted March 27, 2010 Report Posted March 27, 2010 I'm rebuilding my top end as I blew it up last week. One of the domes is pitted pretty good so wanting to order new ones, but not sure what size to get. In the round circle machined part towards the side of the dome it says 21. I take it that means they are 21cc domes? Is that what I should stick with? Here are my mild mods. I would like to know what you all sugguest. Thanks in advance Wiseco Pro lites Toomey filter Boysen reeds Cool Head Pro Circuit pipes Boost bottle (I know, lame) Stock stroke Stock bottom end (as far as I know) The thing came with 19cc domes and I thought that was too much, so I put the domes that are in it now, but can't remember what they were, I'm assuming 21cc since they have the #21 on them?

What fuel do you want to run? what bore are you on? what elevation are you at? what is your timing set at? Quote
zts gixx Posted March 27, 2010 Author Report Posted March 27, 2010 What fuel do you want to run? what bore are you on? what elevation are you at? what is your timing set at? Well it's not bored much, just enough to get rid of scaring on the cylinders. I run premium pump gas, elevation 800ft. Timing is stock as far as I know. Bike is not modded much. Quote

zts gixx Posted March 27, 2010 Author Report Posted March 27, 2010 Awesome....thank you for the info Quote
firebanshee Posted March 27, 2010 Report Posted March 27, 2010 Awesome....thank you for the info Yep, you would notice a BIG difference with the timing mod, cheap horsepower, you can mod your stock timing plate if you know how far to go,(on the top bolt that holds your stator on the washer should be even with the plate for +4) or just buy a plate then you know for sure.
