Hi all, for some time now I've been intrigued with the discussions regarding cams. For instance I have read and it appears many agree the 790 cams are better than those on the 865's. The thing is, why did Triumph change them if they had it right in the first place?
Like, what makes the 790's a better cam?
Personally I prefer to ride with more mid range torque and when I need it, or just because of the thrill factor, a blip on the throttle to get up and go is always brilliant.
Anyway, can anyone tell me why the 790's are better and how do they effect performance? Also, is there any down sides to changing cams as I'm only looking for improvement.
I also read the TBike cams are similar to the 790 cam profile, is that true? Then there are the other makes where there seems to be some doubt on exactly how much better they are etc etc. Certainly, I wouldn't want to fork out the bickies unless I was absolutely certain the investment in extra "fun factor" was worht it.
My reason for asking is, there have been comments that suggest boring out an 865cc motor isn't really worth the extra money and time however, different cams and some head work, and particularly increasing the compression ratio is worth every cent. It makes sense to me as 39cc's extra really isn't big time now is it?
I know all these factors have probably been covered in other threads over the years but sometimes it's a matter of reading between the lines to understand the answers I'm after.
The other area I'm interested in is, the use of some kits with needles that have the circlips to raise or lower them much like a shim.
At the moment I couldn't be happier with how my bike is running but much like being a drug, getting the tweak factor to optimum is always in the back of my mind and considering my last dyno had me running just a tad rich, I was thinking maybe there was merit in it as an option. So any experience on this one would be great also.
Thanks to anyone who can pitch in here and clarify these two queries which I must admit I've been meaning to ask for some time.
cheers
