sheerider11 Posted July 19, 2013 Report Posted July 19, 2013 Any gauge will work. Like I said if you can get a gauge with the threads pretty close to the length of the spark plug that's optimal. But if not your reading won't be that far off. If you can warm the engine up then do it. 1 Quote
250rbanshee Posted July 19, 2013 Report Posted July 19, 2013 Check both cylinders. If there is a 8-10 psi variance between the 2 or if it is low its time for a rebuild. Usually the higher end gauges are more accurate. Quote
Starwriter Posted July 19, 2013 Report Posted July 19, 2013 So, if a compression test hasn't been done, it's a pretty safe assumption that a leakdown test has never been done since you have owned the bike. That would be the next step, after you do a compression test, even if you plan to tear it down. Quote

sheerider11 Posted July 20, 2013 Report Posted July 20, 2013 A 6 minute test to save 600 dollars. It's wrong to not do it. 1 Quote

No, what I meant was its under 2 years old, so it shouldnt really be causing any issues engine wise yet, right? I'm all for looking after my quad, I'd rather do something now than lose later by not doing it. Quote
locogato11283 Posted July 20, 2013 Report Posted July 20, 2013 Time means nothing when it comes to a Banshee motor. They can blow up in ten minutes or ten years. Quote
Uf21 Posted July 21, 2013 Author Report Posted July 21, 2013 If the compression is low, can or will it damage anything or cause more problems? Quote
sstaton1983 Posted July 21, 2013 Report Posted July 21, 2013 If the compression is low, can or will it damage anything or cause more problems? it will make it hard to start to start. Quote
Uf21 Posted July 22, 2013 Author Report Posted July 22, 2013 Will any compression tester do? thinking about getting this cheap on on ebay http://www.ebay.com.au/itm/Engine-Cylinder-Compression-Tester-Set-Kit-Tool-Test-M10-M12-M14-M18-Gauge-/200929778347?pt=AU_Car_Parts_Accessories&hash=item2ec8591aab What is normal compression and what's considered low? Quote
sstaton1983 Posted July 22, 2013 Report Posted July 22, 2013 Around 120. Anything under 100 is considered a dead miss. 1 Quote
Uf21 Posted July 23, 2013 Author Report Posted July 23, 2013 Also would a 14mm deep deep thread compression teseter give accurate results? The br8es is 14mm diameter by 20mm depth right? Quote
Uf21 Posted July 24, 2013 Author Report Posted July 24, 2013 Just a question. If it is low compression is it hard to start when the engine is warm and cold? Quote
Deadbeat Posted July 24, 2013 Report Posted July 24, 2013 no-one is going to dignify that question with an answer, when you where at school..did you fail lunch? Quote
