Nitmare67 Posted April 5, 2006 Report Share Posted April 5, 2006 My trani is locked up in my banshee so im about to split the cases to find the cause. I figure while I already have them apart why not do a 4mm stroker. I would probley just use the plate also. I already have Gorr ported cylinders, 35mm carbs, T5 pipes, V Force Reeds. I figure a stronger crank and why not pick up a few hp and some torque. I am having a hard time finding alot of data written up on the web though about stroker motor building and the pros - cons of different set-ups and such. Where can I find some good solid knowledge?

blueshee03 Posted April 5, 2006 Report Share Posted April 5, 2006 talk to passionre or give him a call .jim is a very wonderful guy to talk to .his number is :918-232-3950 Quote Link to comment Share on other sites More sharing options...
Nitmare67 Posted April 5, 2006 Author Report Share Posted April 5, 2006 I have talked to Jim before he is a really cool guy. I am going to do this build myself though and dont want to waste his time if im not going to be buying parts or using his services just seems rude to me. I figure I will just run the top end as is because it barely has 5-10 hours on it and run the 4mm crank with the spacer plate. I need to measure the height of my exhaust port to determine what spacer I need. I figure this will be a good combo with 35mm carbs, Toomeys, ported jugs and VF3 reeds. What do you guys think?

seb4lo Posted April 5, 2006 Report Share Posted April 5, 2006 your set ut will depend on the porting you already have .... 4MM stroker changes a lot on the timings , so get your porting with a degree wheel or in height then put it here .. And then you ll have the answer , basicly it s not possible to use spacers on a ported engine as you get too much timings on the exhaust duration ...

Nitmare67 Posted April 6, 2006 Author Report Share Posted April 6, 2006 Damnit! I hate it when things just dont go so easy. I already had my cylinders ported and hate to spend money on it again to redo something. Maybe I'll just stick with a 350 but damnit I hate to. Just seems so logical to me to do the stroker now. GGrrrrr. I know Eric Gorr isnt doing anything for a few months either because they are relocating and I hate to send his work to somebody else.

cdwood37 Posted April 6, 2006 Report Share Posted April 6, 2006 I am by far not an expert but i would have to agree that it would screw up your port timing because your stroke goes farther past your port, in turn takes longer to get back down to the bottom.

Wallrat Posted April 6, 2006 Report Share Posted April 6, 2006 You could always pick up some new cylinders off ebay. There's alot of em now since the cubs came out. Or you could do a 4mm cub as well. Quote Link to comment Share on other sites More sharing options...
Nitmare67 Posted April 7, 2006 Author Report Share Posted April 7, 2006 I called Jim today at passion racing. Ive talked to him before but always suprises me how helpful he is on the phone and how much time he spends with you. Alot of shops just want to convince you then sell to you but dont really give a shit. At least around here in cali. Im going to have him set up my cylinders with a 12 port and run the long rod 4mm stroker crank. Cant wait to see how she will rip now. He also took the time to explain the trani to me and splitting the case. I'll let you guys know how she runs in a couple months when I get her all together and running.
