copemech Posted July 12, 2008 Report Share Posted July 12, 2008 (edited) Good to see Ray having a go on the 300! The only other person I know with a 300 Beta could not ride much because of a broken finger, I offered to test it for him? And YES, Heathy, they are required in some areas! I think the one he has is one of the better(less restrictive)ones! Edited July 12, 2008 by copemech Quote Link to comment Share on other sites More sharing options...
cman Posted July 12, 2008 Author Report Share Posted July 12, 2008 All off road vehicles require them. Most motorcycles that are imported to the US have them built in. The trials bikes do not. Thats why we have to add them. Quote Link to comment Share on other sites More sharing options...
yamahaty250xox Posted July 18, 2008 Report Share Posted July 18, 2008 what is the throttle responce like on he four stroke? is it better or worse than the two stroke? Quote Link to comment Share on other sites More sharing options...
jtrials31 Posted July 19, 2008 Report Share Posted July 19, 2008 Only in certain states do you have to have a spark arrester. Like here in Tennessee, we don't have to have them. Quote Link to comment Share on other sites More sharing options...
rlracer Posted July 19, 2008 Report Share Posted July 19, 2008 Cope, sorry I just couldn't allow you to test ride the 300. I seen a stock 250 it put you on the ground (flat ground) within 20 feet of riding it. And I would feel real bad if you got hurt riding my bike ,all the way to the ice chest for a cold beer. I'll let you ride it next time if you bring a permission slip from your wife and a beer. Ray is realy liking his 300 and i'm tickeled with mine.

For your information, I still have that spot on the shin where it hit the bars! I see it every morning in the shower and give RON a good cursing on a daily basis! All the while hearing him snicker in my mind! The TART! But I have yet to get the wifey to open my beer, like you Quote Link to comment Share on other sites More sharing options...
barcota Posted July 20, 2008 Report Share Posted July 20, 2008 ... is that bloody horrible spark arrestor really needed? Spoils the look of the whole bike! Think about it - you never see it when riding. Quote Link to comment Share on other sites More sharing options...
rlracer Posted July 20, 2008 Report Share Posted July 20, 2008 No problem helping you Copie, i'm trained to help the handicaped and those who ride the short bus. See ya in september or october and you can have a go on the 300 with the pipe ! Quote Link to comment Share on other sites More sharing options...

See ya in september or october and you can have a go on the 300 with the pipe ! Ron! Don't let Copie near that 300 till I have a chance to look at it, you know what he does to machinery. All kidding aside, how's the 300 working out, I bet it's sweet. Did you need to do any jetting changes to the CV carb? What type of slide spring seems to work best?

rlracer Posted July 20, 2008 Report Share Posted July 20, 2008 Jon, If you listen to Ray's bike in the video you can hear it breathing thru the air box, he has opened up the air box cover and rejetted. My 300- The 300 kit comes with a smaller main jet, that's all I have done as far as jetting, works great. I have played with the cv carb springs and went with the next one softer from stock but stock works just fine. The aluminum pipe let's it breath and sounds good, not loud at all. You'll have to have a go at the next event Jon, I think you'll come away with a smile ! Letting Copie ride it does scare me ! Quote Link to comment Share on other sites More sharing options...

You'll have to have a go at the next event Jon, I think you'll come away with a smile ! Letting Copie ride it does scare me ! I heard it, nice. The four-strokes are extremely picky when it comes to airbox design and I expect to see a few factory re-designs after the 4T's have been in use for a while. The critical area is around the carb/FI bell, not so much in front of it, as intuition would dictate. They depend a lot on a larger "still air" area than the two-strokes do (kinda like a 4T "big gulp" vs. 2T "constant sipping"), so things like a large radius in the junction of airbox/carb boot is one way to help them out a lot from what we saw on the dyno. The large radius not only shaped the air better into the boot but also increased the "immediate-availability air" inside the filter. I would imagine that the increased displacement would make the CV slide-spring choice less critical, so I wasn't surprized to hear that. I'm glad the pipe still retains a low sound profile, the Beta 4t stock is an extremely quiet four-stroke. Now, if we can just get Honda to retain the services of the Bose Audio Engineers to take some of that bark out of their bite.... Can't wait to try it out! Jon ps. Almost forgot to add that when I did the TC article on your bike, I think I mentioned the observation that it looked like the case/cylinder design appeared to be with the idea of a later displacement increase, so that I would imagine that the added cc's do not compromise the structural integrity or reliability.

copemech Posted July 21, 2008 Report Share Posted July 21, 2008 I just hope someone scratches it before ME! If I give it back to him looking like Ronnie Commo's bike, I will need to buy him some black Krylon! Quote Link to comment Share on other sites More sharing options...
