I finally got the motor finished and fired up tonite. 3rd hard kick and it came to life, a few seconds later puking green all over. i had forgotton to tighten the big hose. fixed that and fired it again, sounds alright needs to be jetted a little but its close. im just happy as hell to hear it run again after a total rebuild. i must say these motors arent that hard to do the bottom end in. its kinda like a chev 350, in that anyone can do it!

Those old frame bikes make really cool looking hill climbers

right on dude. ive never rode the '88. how do they run ?

well i grew up riding oldies like yz 465-490's and before that i did hare scrambles and desert raced a bultaco 370, so compared to those its a dream bike, i personally like the 88's conventional forks to the upside downers for desert riding. it feels so much cushier than the new af's.

ok (danny/bob) so just to be sure now, a 91 crank+rod WILL work in my 88 motor?
because i just bought one. and i still have the 86 short one for sale cheap if anyone needs it. banned500 forum guys get first dibs

all cranks '87+ will interchange, but the '88 and '89 were lighter.. thats the only difference in '87+

dannygraves · Post by **dannygraves** » June 23rd, 2008, 12:54 pm

no one wants the '88-'89 cranks, so the dealers sell them for like $212 brand new... I was planning on buying one before I got the rod kit with bigjays motor.
if you think about it a rod kit is like $80-$100 and to have it installed is like $100-$120.
anyway, glad you got it going, and yes these things are super simple to split the cases on... no need to fear the tiny parts flying out!

dahondaboy · Post by **dahondaboy** » June 23rd, 2008, 2:30 pm

yeah, the cases arent my worry its the fact that i already did it a few weeks ago now i gotta get new gaskets and all that assembly time.
this has a new pro x rod in it so i just hope it will last a few bores before i gotta do it again. i paid 178.00 shipped so i dont think its too bad. i just hope i can get at least 120 out of the short one. why does no one want the 88-91 cranks? are they faulty

dannygraves · Post by **dannygraves** » June 23rd, 2008, 2:36 pm

its 88-89 only, and they are lighter... not good for trail riding, better for a built machine.
Yeah, I spray copperspray-a-gasket on the base, head and center case gaskets, it helps them seal better and transfer heat better, but also helps gaskets come off in one peice and in a pinch or a never run motor, I would just respray them and reuse them as long as none of the mating parts were changed.

this is a hillclimber so lighter might work well for me . ok as soon as it arrives its goin in. now to search for a cheap cyl. thats under 90mm mine is at a loose 91mm
