Tucker0713 Posted January 14, 2014 Report Share Posted January 14, 2014 I've got a new banshee all stock with t5's. I wanna either get a big bore kit or stroker kit(can't afford both). Which will work with stock carbs better. Which one should I get for drag, I've already got heavy clutch setup on the way and I'm still deciding what length swingarm to get. Give me some recommendations. And is there a way that I could get a stroker kit then later get a big bore with out complications and vice versa with big bore then stroker.

WINDYCITYJOHN400 Posted January 14, 2014 Report Share Posted January 14, 2014 +4 Stroker crank. You can go to a blaster piston and jump into that bigger size with the stock cylinders. +6 arm. Quote Link to comment Share on other sites More sharing options...
shanYE west Posted January 14, 2014 Report Share Posted January 14, 2014 To use stock cylinders and blaster pistons, you would have to bore your cylinders to 66mm.. Waste of money not to mention cylinder life.. Buy the long rod +4 crank, use 795 pistons and get porting done. When the time comes for the big bore.. Sell the cylinders and buy a cub/serval kit and use your bottom end. A well ported and setup stock cylinder 4mil will rip. you probably wont even want a "big bore"... well.. probably will.. but at that point you'll go past a 421..

oldskool Posted January 14, 2014 Report Share Posted January 14, 2014 Yep, start with the 4mil crank and bore stock cylinders to the next size piston and have cylinders ported for extra stroke. coolhead with domes is nice mod also. It will allow you to play around with compression. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 14, 2014 Report Share Posted January 14, 2014 Stay away from big bore kits for stock jugs. Get the 4mm crank and port the cylinders. My last motor was a big bore in stock jugs. What a nightmare to keep it sealed up past 68 mm if you wanna run any compression and timing. My current motor is 4mm ported stock cylinders and it is far ahead of what my big bore was capable of doing. The only difference is my new motor is 40/50 CC's smaller so there was a bit of a displacement advantage which helped lugging it out of a turn or up a hill. But that's fixable with a bit of clutching. If you want more then the stroked ported stock cyls can give ya, then get a new monoblock type of cylinder and move up.

Don't know what you're thinking for budget, but you should plan on about $1,000 for crank, pistons, bore, porting, gaskets, seals,modded trans, domes, etc. If you don't have that to spend, you need to rethink where you want to go with this.

Tucker0713 Posted January 15, 2014 Author Report Share Posted January 15, 2014 Thanks for the response, I saw in a previous post someone mentioning running nitrous, could this be done with stock carbs? I doubt it but I'm curious. And does anyone know somewhere I could send my cylinders to be bored for a good price. Don't have any shops close by to send them Quote Link to comment Share on other sites More sharing options...
m671054 Posted January 15, 2014 Report Share Posted January 15, 2014 You can run nitrous with stock carbs. the 2 are totally unrelated. Quote Link to comment Share on other sites More sharing options...
