Hello Paul,
Did you ever find your grandfathers machine?

Kenneth Winter
USA..
Recently toured Scottland. AMAZING!
I would love to return and work/stay longer..
How would an American do that???

It time to buy my secondary clutch, shafting and bearings.

It would appear that shafting with key way is the best options for sprocket options.

So where can I buy at Team Secondary Clutch with a smooth/keyed bore?

Welcome Tristan,
It looks like we are the freshman class here.

I am beginning my long awaited build too..

The aixam engine was one of my top engine choices.. But we dont get them here in the US..

Are you in England?
I would love to visit there for a diesel bike rally..

I bought my Guzzi based on the build criteria for my diesel bike. I went to a Huge motorcycle consignment shop. Used bikes.. The 70 year old owner took interest in the diesel Idea.. We talked about what would make a good donor for such a project: Needs: Heavy frame The largest hole to mount the dies...

Hello Group! My name is Kenneth Winter. I live in East TN, USA. Forgive me for failing to introduce myself, before posting in the build sections of the forums.. I have enjoyed reading the posts by the members of this group. The collective wisdom here is amazing. Upon reviewing the many insightful po...

I had hoped to avoid cutting the frame for the diesel install. That is not going to work, so I will modify as needed.. Right now it appears if I moved the whole engine forward 6 inches, I could use the CVT system. It would require removing and modify the front two down tubes. This will allow me reta...

GuzziJohnO is a steel working artist.. Beautiful work..


What are the frame connection points called?
Did you buy or make these?

I have studied this system.. Interesting.
But I dont have that much space..

I still have not found a good explaination of when to introduce the RPM increase into the system.

It appears the diesel utv and snowmobiles modify the final drive gearing..

I would love to attend a Diesel bike event.. I am in TN. Having hosted various events I can tell you it is alot of work! The host will not enjoy the activities due to the work load. Might I suggest piggy backing the DIESEL GATHERing with some other LARGER motorcycle rally or gathering. We could be a...

RON. From the archives............... another study below of a project that shares some features with yours. While it's a snowmobile, it's using the D902 and a CVT. Noteworthy is the power and torque. Using a turbo and D1105 pump parts, they dyno'd at 55 hp and 78.4 ft. lbs. of torque at 3900 RPM. T...

Great minds think alike. I was studying snow machined. Snow machines have had CVT for years and there seems to be MANY more after market parts for them. Here in TN... I have never seen one... No wait.. we had a neighbor moved to TN from MI.. They had a snow blower and a snow machine for sale in the ...

I would love to here this groups opinion on what to change in a CVT primary and secondary Clutches for our diesel application..

Primary :
Weights
Helix
Springs
Belts
Rollers



Thanks for you input.

Tappy thanks for the post. I have a good understanding of how a CVT works. But tuning for the diesel is confusing. 1. I can see how the CVT responds to RPM.. And thus a difference for the diesel. Question.. 1. Size. What determines the size of Disks to use? I have tiny ones from scooters and a Massi...

CVT considerations.. I am building a diesel bike.. I am pondering at CVT drive. The common issue with Diesel applications is the lower operating RPMs. This post is about HOW and Where it introduce the RPM increase into the cvt system.. ie do we Step the RPM up before or after the CVT? For my project...

Did you build this cool machine??

CVT considerations.. IF I can find an appropriate CVT for my application, I have a question about How the CVT works.. Constraints: 1. My nal rear end ratio is set at 1 : 4.625 . Shaft drive. 2. Diesel engine rpm is 1/2 the gas engines rpm. 3. Due to the lower rpm of my diesel engine I calculated I w...

1. A "high" ratio final drive is in regard to the ratio (e.g. 1:5). The RPMs delivered to the wheel are 1/5 that of the engine RPMs. A high ratio final drive should not be confused with thus producing a "high" speed. Quite the opposite. It will result in a much lower speed than a...

I have the Specs for the stock motorcycle gear ratios. Do most motorcycle transmissions run greater than 1:1 in the highest gear? Click to zoom in.. stock gearing.PNG 4 gear is 1 : 0.0869 5 gear is 1 : 0.0750 If I am reading them correctly 4 and 5 gears are greater than 1:1. Meaning over drive - out...

TET "I doubt that the current FD ratio is to tall for your diesel but if its really that high up, don´t change anything." It is this assertion that has me confused.. This is why I am trying to pin down the drive line gear ratios" klwinter2 wrote: The numbers from your gear commander s...

Right angle gear boxes - power loss

How much power is lost every time you transition through a 90 degree gear set?

15% ?

gilburton "In the 2nd pic with the engine across the frame does it not have to be round the other way to get the correct rotation?" Maybe.. the engine turns anti-clock wise ( looking at the flywheel). The drive shaft turns clockwise ( from the engine side). "In the inline position it ...

RON, "a study in shaft-drive offsets" Great information.. I suspect I will end up with a lay shaft.. I think it is the best solution to fine tune the final gearing. I am still struggling with the Gear charts.. Argg.. A good understanding is needed before I build my trans/cvt/gearbox. Kenneth

Allow me to filter through the questions: 1. Ron- Turbo and super charging - Hopefully by going with the larger displacement of the D902 force air will not be needed. This will avoid expense, complexity and promote longevity. 2. Ron- Have I seen Garbs 722cvt CX500?.. YES..Amazing work..I would love ...

I finally bought in! You can only read so much and then you have to BUILD something. After reading for hours about all of the options to consider when building a Diesel motorcycle, I spent my mad money on the following parts. 1. Donor bike - 1974 Motoguzzi GT800. Why? It has a Huge hole where the en...

I was so sure the Kubot D722 was the way to go I bought one and a frame to start my project.. The goal was a machine that would be able to cruise a 75 mph and 2500 rpm.. Now that I have run all of the calculations, the number say the D722 is just to small/weak.. I am surprise and disappointed.. I se...
