Basicorpse Posted April 21, 2005 Report Posted April 21, 2005 (edited) I threw a rod on my shee and destroyed one of the cylinders and piston. One of my rods are also bent. The crankcase has a few grooves in it but seems to be usable. I am thinking about doing either a 4mm stroker crank and getting it ported over the winter. Or just getting new ported cylinders and pistons and grab a cheap stock crank. What do you guys reccomend? Edited April 21, 2005 by Basicorpse Quote
sredish Posted April 21, 2005 Report Posted April 21, 2005 What do you guys reccomend? 358416[/snapback] all depends on what's in your wallet... porting + stroker is obviously more power than portwork alone so just figure out what you can budget for it... Quote

decon Posted April 21, 2005 Report Posted April 21, 2005 building a stroker will definately cost more than 800 . stclark highly recommends a Eric Gorr port. Best bang for your buck at 200. he ran toomeys with his port job and says it ran awsome. i would get the eric gorr woods port, stock carbs bored out to 28mm, some new pistons, and a noss machine head.

How much power increase will I see with stock porting? What if i just have a regular mx port on the cylinders done will it affect anything with the stroker? Edited April 22, 2005 by Basicorpse Quote
decon Posted April 22, 2005 Report Posted April 22, 2005 (edited) im not a know it all but you need porting to make up for the added stroke. w/o stroker porting its basically useless, you wont get the full potential of your stroker. i really dont think a mx port will get the full potential out of your stroker either. your machine will need larger carbs and bigger intakes with the stroker. you will also have to cut 2mm off the top of your head, or have 2mm cut into a pair of domes for an aftermarket head. you might get some power increase but not alot. a member on here did the same thing your thinking about, except he had larger carbs w/ no porting. you can do it and just save up for some stroker porting and bigger carbs. oh and by the way that kit on ebay isnt a 4mm stroker crank, its a +5mm long rod crank. 5mm long rods are susposed to increase the realiability of your motor, but I dont think its needed for a 4mm stroker.

Nothing raised or lowered. Running stock carbs and airbox with lid, Fatties, Trinity modified stock head at 150 psi compression. +4 ignition timing. Runs like a raped ape. Will out pull nearly all of the ported 350s I have run, except the ones on alky.The lowend throttle response is phenominal compared to the 350 engines. This combination is a good all around engine for trails, climbing and MX. With a mild port job and a higher comp. ratio, it will get with the business. I have run T5s on this engine with good results, just not nearly the lowend response, but with more over rev. I have a set of taper bored carbs to sell,or I can bore your's, if you are interested Pm me . Quote

Or at least they are rifled they have a spiral like pattern machined into them. Like that when I got the bike. I have t5 pipes already so that should be good I heard they respond well to porting. Is your porting stroker specific or is it just general porting? Who did the porting for you? I am in need of 1 cylinder should I just buy 1 and have them bored to match each other or buy a pair? Also thanks for pointing out its not a stroker crank I just saw the +5 mm and automatically thought stroker. Big mistake, although it does come with spacer plates so it must increase displacement some. Quote

And stick with the stock stroke crank. You will have a excellent running machine with good porting. You have pipes that are compatable with porting and you say you carbs are modified. That should all work with your set-up without breaking you budget. Good luck on whatever you decide. Edited April 22, 2005 by duecebanshees Quote
