stewart3871 Posted January 7, 2005 Report Share Posted January 7, 2005 has anybody got any info on how to stop 'pinking'. I have an 03 rev3 250, which runs fine most of the time but when its working a bit harder, or on uphill climbs, or held on a constant throttle on flat ground, it develops that annoying metallic knocking sound, that i think is pinking. Running the bike on PJ1 Silverfire semi-synthetic, at 70:1 as recommended. Any advice would be appreciated. Quote Link to comment Share on other sites More sharing options...

m4rt Posted January 7, 2005 Report Share Posted January 7, 2005 (edited) Stewart3871 (what kind of name is that?) Sounds like something you buy at Boots. Anyway back to the pinking problem. Carefull about taking carb advice from billT. He is a Scotti and rode a Beta for many years, I guess that says it all. In future just e-mail me directly and I can help you out with any techy question you might have. I have just struck a deal with Andy to be his onsight technical guru. He supply the punters, I answer the question and he gets the small fee that is charged Start firing away with the questions.

neonsurge Posted January 7, 2005 Report Share Posted January 7, 2005 At the risk of stepping on the toes of the great all-knowing oracle M4RT (ahem), I had this exact same problem on my '03 Rev3 and solved it by simply going up one size on the pilot jet from 30 to 32.5. As HondaRS mentioned, using a higher octane fuel helps (but didn't cure it completely for me). Good luck! Quote Link to comment Share on other sites More sharing options...
rlracer Posted January 8, 2005 Report Share Posted January 8, 2005 A club member here had a pinging problem and when I looked at it, it was something simple. He was running vent tubes and they were clouged at the ends with chain lube and dirt. Once cleared the bike ran fine again. Quote Link to comment Share on other sites More sharing options...
clarkp Posted January 8, 2005 Report Share Posted January 8, 2005 (edited) Sch-tewart - do a search in the BETA forum for 'pinging' At the top of the Trials Central page, hit Search On the Search page, enter pinging as the keyword Set the Search Where to Bike Specific ..BETA Set the Search Posts From to Any Date You'll hit nine good threads on the topic. So, to answer your question, yes. -cp Edited January 8, 2005 by clarkp Quote Link to comment Share on other sites More sharing options...
stewart3871 Posted January 8, 2005 Author Report Share Posted January 8, 2005 (edited) many thanks for all the info lads. it seems there are 3 things i should try having read all the threads relating to this topic; need to try shell optimax fuel, possibly a champion n7ycc plug, and maybe increase the pilot jet. (once i get the carb off & see whats in there at the moment) Once again thanks for the info, i'll let you know how i get on next week. P.S. sorry about the name M4RT, I'll try and come up with something a bit more trendy! Edited January 8, 2005 by stewart3871 Quote Link to comment Share on other sites More sharing options...
stewart3871 Posted January 8, 2005 Author Report Share Posted January 8, 2005 thanks hondaRS, thats the way i'll do it. P.S.Did you receive my sae ok for the beta handbook? Quote Link to comment Share on other sites More sharing options...

dabmeister Posted January 9, 2005 Report Share Posted January 9, 2005 If I don't use Super Unleaded in mine, it sounds like there's a bag of ball bearings loose in the top end under load. Quote Link to comment Share on other sites More sharing options...
stuessenhigh Posted January 10, 2005 Report Share Posted January 10, 2005 Hi Stewart.. the Champion plug DEFINATELY works better on mine..and our Beta importer here in Hong Kong was told to ALWAYS use the Champion...but I think the best thing i did (mine used to ping as well) was to switch to better petrol. Makes a big difference. Good luck! Quote Link to comment Share on other sites More sharing options...
stewart3871 Posted January 10, 2005 Author Report Share Posted January 10, 2005 thanks dabmeister & stuEssenhigh. going to try the super unleaded, but it wont be until this weekend. (work keeps getting in the way of my socialising!) Quote Link to comment Share on other sites More sharing options...
