Tyshooter2000 Posted March 9, 2017 Report Share Posted March 9, 2017 Hello everyone I am new to the forum so bare with me. I bought a new Banshee three weeks ago. The thing is pristine honestly looks like it came off the showroom floor. Starts first kick every time. I took it out riding and beat the hell out of it at the supercross track and it performed beautifully. Got it home and for shits and giggles I did a compression test. Both cylinders test at exactly 89 psi. That seems low to me but it does have stock heads stock Pistons and stock rings. Is it time for a rebuild? Or don't mess with a good thing and use her till she dies? She runs beautifully idles perfectly and doesn't smoke bad at all. Any input would be great. Thanks.

hoppedupandcutdown Posted March 9, 2017 Report Share Posted March 9, 2017 And test with both plugs out, wide open throttle, kick until the needle stops climbing. Quote Link to comment Share on other sites More sharing options...
Tyshooter2000 Posted March 9, 2017 Author Report Share Posted March 9, 2017 I rented a tester from autozone Quote Link to comment Share on other sites More sharing options...
Ducman Posted March 9, 2017 Report Share Posted March 9, 2017 Probably an issue with the test gave the low numbers, but getting an equal pressure on both sides is a good sign. I have a similar issue with my cheap compression tester. TDR recommended a few specific models and the craftsman compression tester was one, its affordable, about $65.

Tyshooter2000 Posted March 9, 2017 Author Report Share Posted March 9, 2017 Thanks guys I guess my question is nothing to worry about? I would like to get another solid year out of her before I do a complete rebuild. Think that is achievable? Especially since it is running so well?

Tyshooter2000 Posted March 9, 2017 Author Report Share Posted March 9, 2017 It is exactly even as well so I guess that is in its favor Quote Link to comment Share on other sites More sharing options...

Tyshooter2000 Posted March 10, 2017 Author Report Share Posted March 10, 2017 Thank you gentlemen. I went back to banshee after running a ltz for many years. Just am a lover of two strokes. So since my bike is probably good to go my next idea is to get some Vito's cool heads and a oversized radiator and high performance water impeller. What are your guyses thoughts?

bigweav81 Posted March 10, 2017 Report Share Posted March 10, 2017 Go for a head that doesn't require stud removal / changing. Noss, chariot, or driveline....if your head hasn't been milled they can cut your stock head. Look into it.

bluebanshee98 Posted March 10, 2017 Report Share Posted March 10, 2017 For a oversized radiator look on eBay. Going to be around 65-75 bucks. Price has gone up over the years. They work great and well worth the money. I got a couple for like 55 bucks a peice a few years ago with no issues to this day Quote Link to comment Share on other sites More sharing options...
Tyshooter2000 Posted March 10, 2017 Author Report Share Posted March 10, 2017 Thank you blue that is what I will do then. I will get the radiator off eBay and all the supporting mods and do a complete rebuild in a year or two. Blue do you have a set of cool heads as well? Or do you think a high volume water pump and radiator are enough? I live in Michigan so it isn't like Arizona temperatures. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted March 10, 2017 Report Share Posted March 10, 2017 ebay radiator and aftermarket pump here as well. Works great. I didnt go with the fancy silicone hoses. I use the cheap black NAPA stuff out of principle. Radiator and pump should be enough when tuned properly and you keep moving. Quote Link to comment Share on other sites More sharing options...
