I did not make it clear enough in the video but the 3 piece wide crank was not installed in the Raleigh Big Horn because the 4G T Belt Drive Engine kit was purchased to be installed in a Felt MP Cruiser.

Hope you enjoyed my videos

Here is the latest customer build by Charles Breaux Aug 5 / 2010




Nice work Charles

Here is the latest customer build by Chris Beam May 25 / 2010




Chris has done a nice job on this install he listened to all my install advice and and did every thing right and has no need for useing chain idler. Now the engine looks real good but he has removed the cooling shield. And as soon as I saw this I contacted Chris and told him that this removing of the cooling sheild will cause the engine to over heat on this side of the engine causing one valve to fail so he is going to put it back on right away. I love the cool mod he has done to the cover of the T Belt it is one of the latest things that people have been doing to the 4G.
GOOD JOB CHRIS YOU SHOULD BE PROUD OF THIS INOVATIVE BUILD

My review of the 4G T Belt Drive Engine  Kit

The first thing I would like to say is that it took me a long time to make the decision to change from a 2 stroke to the 4 stroke as I really like the looks of the 2 stroke, it just has that look of a motorcycle. Having said that I decided to take the plunge and make the change to the 4 stroke, so I went looking for a supplier (on the net), I decided on the 4G T Kit after comparing all the gear drive ones and I am completely happy with the 4G T Kit it just made sense, no gear noise and no gear on gear grinding. I selected www.blowbyumotorizedbicycles.com as my supplier after calling a few of the other suppliers to ask the normal stupid questions I had about the kit just to talk to some answering service, Terry at blowbyu is easy to reach and it was nice to talk to someone that builds and rides a motorized bicycle.

Now about the kit, I found the kit very easy to understand and easy to install with only an occasional look at the provided instructions althought the crank assembly could have had a few more photos, althought once you pre-assembly the system it all becomes clear how to install it. The kit seems to be well thought out and all the parts well made especially the transmission. It took me about 6 hours to install the kit test run and dissemble to prep for the new paint job. The kit comes with a 50 tooth rear sprocket but I opted to use a 44 tooth sprocket that I had, I can cruse quite easily at 35 mph and have reached a high of 45 mph. Now the pros and cons, p1- motor starts with just 1-2 pulls, no more pedaling to start, p2- motor seems able  to pull the hills that I travel 3 times per week here in Al with no problem, p3- I can reach the speeds that I was looking to achieve without the engine screaming, p4- with the long pipe its so quite that I can now hear my I-pod, p5- no more pre-mix (I save about .50 cents per gal on gas), p6- I can actually see clearly in my rear view mirror, no vibration and no more arm pump. Cons, none to speak of other than my original that I like the looks of the 2 stroke, but now that I have completed the install I am completely happy with the results and if you look at the pictures of the bike it shows that if we let our imagination loose we can achieve whatever we set out to do. This has been my first ever review (easy to tell huh) I hope this review has helped you and if you decided to go 4 stroke have fun and let your imagination free. I give this Kit a 5 out of 5.




Bob
This is an impressive looking bike, it looks like the 4G was made just for that bike your going to turn a lot of heads with it Cheer's

Hello Terry,
I got the billet grips from you last week.
Have to say they look nice on the bike.
They function well. Went on with only one mod needed,drilling the pin hole larger.
Quick and easy way to add a lot to a motorbicycle.
I think if folks saw your site they would like it. Has some thing others don't have yet or don't have pictures of. Yanks seem to think a picture is worth a thousand words.
Let them see what you have. Get some reviews. Your PR is 2nd to none. Of course you may be opening Pandora's box.
Thank for the preview and again for the grips.
Lloyd

Alex Matiaco Review

I had purchased a 2 stroke motor kit from an on line website, and was putting it together. I came across a bunch of problems that I did not know how to deal with so I searched online to try to find a solution. Somehow I came across Terry Blow website and sent him an email to see if he could help me. I was not really expecting to get a response because I had not received one from the company that I bought the kit from in a few days. Terry responded to me the next morning, I was shocked to get help that fast. Terry helped me fix all my problems; he even had me call him late at night to explain how to put things together. Terry has been a great help and without him I could not have finished my bike.

Thanks a million Terry!!
