FWIW: I have 1 LT80 that was modded by LRD ... LRD port work, DG 20mm carb W/clamp on K&N and DG pipe (now stock pipe). I did another stock LT80 myself ... a little port & head work, modded the stock carb and did some clutch work ... all stock air ducting, filter & pipe ... it was as fast and maybe a bit faster than the LRD bike ... Works makes LT80 shocks but 1 set of shocks is more than I have invested in my 2 quads combined ... you'll have a funky suspension with great shocks
... I think Predator 90 & maybe Kasea shocks can be fitted to the front ... the back shock has odd mounts.
Youngsters & newbees are hard on the clutches slipping them a lot with cautious slow starts. I gotta sand the glaze off after every family reunion. Just hammer it, hold on & go is the best & most fun
Stock petcock can be a pain as it relies on carb vacuum to operate ... leave the petcock on prime & put a cheap lawnmower type shut off valve in the fuel line.
BTW: about drilling holes in your airbox ... Jack Moore claims 11hp @11,000 rpm with stock air box & stock pipe .. something to think about!
can prolly lean it out a bit ... plug chop
.030 off the head is a simple gain..
silly story: told the kids I could make the LT80 faster with a file ... no way they say ... LOL ... took the head off, got out a big nasty file & took off .020 ... cleaned it up with a smoother file & lapped it flat ... oh, to prove a point ... coulda just put it in the lathe and reshaped it proprerly but where's the fun in that
