platinumjason Posted May 16, 2006 Report Posted May 16, 2006 (edited) I just thought about this and was wondering, how many horse can I run before I should consider getting my crank welded? Currently I am running a stock motor with Vforce 3 reeds, K&N with pro flow and stock box/lid and timing advanced 4 degrees. The cylinders I am getting are RDZ ported Level 2 rated at 80 horse... With all my stock parts plus the few little upgrades I have now, will it keep the power low enough to not ruin my crank? Edited May 16, 2006 by platinumjason Quote
scotts96fast Posted May 16, 2006 Report Posted May 16, 2006 Most people say with porting,pipes,carbs,reeds and other bolt on mods you should true and weld the crank.i've been running the stock crank for 6 years now and no problems.But than i crack the caes every other year.So far I just replace one outside bearing that was going.I might crank it next year,but I'm not sure what kind of crank.I don't think it will be a hot rod thou.

platinumjason Posted May 17, 2006 Author Report Posted May 17, 2006 Yeah I think Im only gonna get 50-60 tops. Gonna run it this summer and tear it down in the winter and do it. Quote
rocketboy Posted May 17, 2006 Report Posted May 17, 2006 level 2 porting at 80 true hp on a stock stroke ? i doubt that unless theres some methanol or nitrous involved .id get the cran k welded regardless Quote
platinumjason Posted May 17, 2006 Author Report Posted May 17, 2006 (edited) Yeah, I know the odds of me hitting even 60 with the mods I have will be unlikely, just wanted to see everyones thought about getting the crank welded. Found a guy on planet sand 2 hours away that will tear my motor apart, weld the crank and install my new jugs and top end for $175. Seems like a pretty fair price. Just a ways to drive.

platinumjason Posted May 17, 2006 Author Report Posted May 17, 2006 Yeah, hopefully he knows what he's doing. Quote
platinumjason Posted May 17, 2006 Author Report Posted May 17, 2006 Also, one of the stud holes has a heli coil in it. will this things hold up? Hope so anyway haha. Quote

Dark Ranger Posted May 18, 2006 Report Posted May 18, 2006 Amen to that. Helicoils are the cat's meow if you strip the threads out of a hole. Quote
Toybreaker Posted May 18, 2006 Report Posted May 18, 2006 Heli-coils or if your machinist has them ask for a keensert. they are even better than heli-coils. Last time i did the top end on my shee i put helicoils in all the holes for the jug studs. When i replace the crank i am going to heli-coil all the case mating holes too. Quote
[email protected] Posted May 18, 2006 Report Posted May 18, 2006 50-75 hp , but if ure engines open mine as well weld it up when ure at it , only adds more reassurance and less $ down the road ...... do it right and have no regrets Quote
