bananahamuck Posted October 15, 2015 Report Share Posted October 15, 2015 I'm confused as to why one would bag on innovation... If you are refering to me giving my many,, many years of working in and around many sizes of roller chain type, bearing chain sprocket idler pulleys of every size conceivable ,, i'm not talking manure spreaders............ Well i ask you this,.... Why has no major auto manufacturer ( with their trillions of dollars in R&D and zillions of test miles) use a bearing chain sprockets on their major timimg chains and opt for rubbing blocks??? Or even most motorcycles ever ,, on their main drive chain ,??? Answer ,,, i already stated it in my earlier post. Bagging would be me saying i don't like it with no prior experiance to back my statement up,,,,,,,,,,,, i was stating fact that i have seen in person and re-engineered stress points to alieve stress and slightly improve bearing life. and just labeling something "off road only" that is going to be a detriment to the running of a car if it suddenly fails,,,,,,,,,,,,, does not change the fact that I still think it is a bad idea to use one in your engine in my OPINION. If your not talking about me,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, well there you go. :rofl: If Mattendew didn't want opinions he should have just made them,, labeled them off road only, and sold them,, but he put this in discussions,,, so i gave my .03 cents Do what you want . 3 Quote Link to comment
Draker Posted October 15, 2015 Report Share Posted October 15, 2015 Perhaps modify it with a friction bearing and an oil passage. * <--- Royalties can be sent this way. *User does not have background in automotive or mechanical engineering and should not be taken seriously, unless said ideas prove to be valid. 1 Quote Link to comment
Mattndew76 Posted October 15, 2015 Author Report Share Posted October 15, 2015 I will say that bearing grades have a huge to do with failure I agree with you Nanners, but some items are not meant for daily grind. Just because it is labeled for race use only doesn't mean its intent is to skirt quality or lack of proper engineering. It just means more attention to the motor on a daily or per engine use is needed. your assessment of the roller system being not in use may be a little off base. Most modern motors on the road now actually employ a roller or idler pulley for the Kevlar belts or chains for a timing system. Majority is a HTD Kevlar belt. But in those systems is a bearing or bearings that have the ability to withstand 40,000 RPM on a daily basis. Can this be added to an L motor. By all means yes and would have durability to boot.

Mattndew76 Posted October 15, 2015 Author Report Share Posted October 15, 2015 Usually friction slides have to be added due to angle tension and economics. far easier to produce a friction slide than a roller system. The bottom image is a motor that employs both a friction slide and a roller. Here is OS Giken with a an all bearings roller gear setup. Quote Link to comment

Love the small print. Kameari thought of it too. 2 Quote Link to comment
Lockleaf Posted October 15, 2015 Report Share Posted October 15, 2015 Not you man, sorry, I kinda wondered if I came across wierd. Cruznude seems to think being the first guy with a new idea is a bad thing. I thought that was odd. 1 Quote Link to comment

Mattndew76 Posted October 22, 2015 Author Report Share Posted October 22, 2015 So work is going to start on the 51mm ITB's this coming Monday. All fixtures have been designed and start milling them today. They have the provisions for the idle control valve. Any Investors? Quote Link to comment
Lockleaf Posted October 22, 2015 Report Share Posted October 22, 2015 51mm itbs for which motor? Sorry if you stated that and I missed it. Quote Link to comment
Mattndew76 Posted October 22, 2015 Author Report Share Posted October 22, 2015 They are universal ITBs. The back side has a clamp ring surface for rubber ring mounting. I am making 2 for the 1200. next week. Gotta turn the mill into a lather for the butterfly shafts. 1 Quote Link to comment

Mattndew76 Posted November 8, 2015 Author Report Share Posted November 8, 2015 Ok so I started on the Auto TB concept today. This is what I have so far. Just concept modeling so far. Ever seen Shaft-less Throttle Bodies? 7-10% better flow than conventional shaft supported aperture. 4 Quote Link to comment
Mattndew76 Posted January 14, 2016 Author Report Share Posted January 14, 2016 Making a few of these for the 1200. 5 Quote Link to comment
cruznude Posted January 15, 2016 Report Share Posted January 15, 2016 can you make some polished aluminum pulleys for my 620 crank and alternator? 1 Quote Link to comment

Mattndew76 Posted January 15, 2016 Author Report Share Posted January 15, 2016 Would have to buy some form mills, and a Lathe would work much better than a 3 axis Mill for making those. But I could YES. Does no other place supply a slick pulley kit for the L-Motors? 1 Quote Link to comment

G-Duax Posted February 4, 2016 Report Share Posted February 4, 2016 Im hunting for these McMaster-Carr, and just about any bearing supply. Called a spherical bearing. How is the chain tensioner project coming? Do you know Kamari makes like 3 versions of theirs to fit different inspection cover locations in the head. I have 2 styles. God I hope I have the correct one for my head....... The difference is in the location of the top sprocket on it's slide. 1 Quote Link to comment
