Really lean..? Now what??
I PM "JETPILOT" and he gave me some asnwers (bold letters) to a few questions I had on my 929..... my question now is what do I do about a lean running bike?? Oh and he wanted to know what add on part were installed....nothing major... Flapper removed and HTEV wires in midrange position, NGK iridium plugs. K&N filter(I think) and a two brother racing muffler.
So I just had a few questions regarding this bike (929.) I got mine running well again and tonight I was sitting on it revving and what not and held it at about 9-11 grand for a few. I noticed that the headers became red hot....and I do mean literally RED. Normal?
when it gets red like that at high rpm's , that mean it might be running slightly lean...if the pipe isn't red at idle or up to about 6000 rpms, but is red above that then you need to raise the jet size.
The second is, should my engine and exhaust get a bit distorted when at high RPM's?I dont want to say backfiring but its like it wants a wider pipe...you know? It sound so low and rumbly and rock solid anywhere below say 8 grand but up about it gets raspy....I know that there is alot going on at that RPM but its nice to hear its normal......is it?
another lean condition symtom.
The third is what temperature should I start being concerned with on my digital temp guage? I know the fan kicks in at 215 but when does it become to hot......tonight I had it up to about 235...
235 is too hot...shouldn't get above maybe 225, another lean symtom.
Anyways just a few question, I dont think anything is wrong but they are noises and particular things about the bike Im not used too.
Any help would be cool,
