heffergm Report post Posted November 25, 2016 ROFL. First thing out of the engineer's mouth is 'What the riders wanted was unreasonable'. How Honda is that!?! You'll take what we give you, damnit! Quote Share this post Link to post Share on other sites
heffergm Report post Posted November 25, 2016 Didn't realize the factory bikes were twin plug. Is the production 4rt as well? Quote Share this post Link to post Share on other sites
jonnyc21 Report post Posted November 25, 2016 (edited) No the production bikes are all single plug. Edited November 25, 2016 by jonnyc21 Quote Share this post Link to post Share on other sites

sportsawyer Report post Posted November 26, 2016 The way I read it they didn't need the twin plugs until they increased motor size to 313cc. That's what I got from the text. I'd suspected they had separate maps for each plug, and apparently that's the case. So there can be a lot of control of the burn by changing how the plugs fire as a function of TP and RPM. This new works engine was first used in FIM competition in 2013 -- the first year of the new no-stop rule. Don't know if that had anything to do with it. Another change in that engine is cases that have clutch slave cylinder mounting on the left side. So the clutch configuration can be similar to a 315r, CRF250R/450R, Beta, Sherco, ... with pushrod through the main shaft. If you look back at WTC photos from 2013 on, Bou used the new clutch configuration for part of 2013 and then went back to the same clutch-cover actuation as stock bikes. Fujinami used the newer clutch longer, but has been back on the clutch-cover actuation for a while now. All competition photos I've seen of Busto -- when it could be determined -- show him using clutch-cover actuation. The interview had some vague wording about importance of clutch in trials. But didn't go into the use of left-side actuation and going back to clutch-cover actuation. If you look at current photos, you can see a simple plate covering the slave cylinder mounting location on the left side, and clutch hose / banjo bolt / etc. on the right side of the Repsol-Honda Team bikes. 3 Quote Share this post Link to post Share on other sites
markg Report post Posted November 26, 2016 To chime in on an older post: Are you saying there is no wiring between ECU and the injector? The latter is fired/triggered over Bluetooth connectivity? Quote Share this post Link to post Share on other sites
jonnyc21 Report post Posted November 27, 2016 Ah the wonder of wireless, if only I could get a Bluetooth connected PTB for my Montesa and future 300RR. I am sure it would be for the most part wasted on me but would still be way cool to have the bragging rights on that one. LOL Quote Share this post Link to post Share on other sites

jj65 Report post Posted November 28, 2016 quick release clutch hoses do they still have those?[/quote Brake hose too, that's for crash damage, straight swap for new handle bars with master cylinders, levers and twist grip. Quote Share this post Link to post Share on other sites
martin belair Report post Posted November 29, 2016 (edited) Well if you make it to Kingman next year, you will get to see the engineers chase Fuji and Bou around. No need for that Bob. Maps are available and bikes are ready to go. It's an easy swap to do before you get there. If you do it at all. I was just at the TdN at Isola 2000 meters, (6000 feet ). No need for engineers chasing anybody. You need to get up to date Bob. Your last World Round was what 10 years ago. Speaking of chasing, I seem to be chasing you a lot lately ...........

lineaway Report post Posted December 1, 2016 (edited) I scored Tennessee in `13 and watched Fuji and company during practice being chased by which engineer? Fuji was p****d off at the bike! Seemed to be the new two plug engine. Lap top in hand. Or was I just dreaming that a laptop could fix his problem? PS. Martin there is nothing wrong that EFI bikes make last minute adjustments at that riding level! Edited December 1, 2016 by lineaway Quote Share this post Link to post Share on other sites

paul7 Report post Posted December 11, 2016 The interview in the link that's posted says 2013. I would think it's hard to notice the twin plugs because one sits directly behind the other, not to difficult to see the twin coils though. Quote Share this post Link to post Share on other sites
