Morini Time! Full sus project!

Sorry I never answered your question clearly. There is not much info on the forum regarding the durability of my design. Having to find out for myself. Will post my results clearly and truthfully when I get to test it. This was based on SBP jshaft experience that inspired this approach.

Well Gh, It`s Like The Monkey Said When His Tail Got Cut Off By The Lawn Mower; It Won`t Be Long Now!! You Will Be Celebrating Soon!! Just Finished A 7 Speed Shifter, Sure Works Cool. Ron

Got about 20 miles on this pig and I love it! The two grocery stores near me still let me walk through the store with it. I lit up on it once going up hill for about 300 yards man it is quick! Been pampering it for break in. The kick hand start just hit it once and it starts right up.

The suspension is working just the way I had hoped. I don't notice any bad vibrations from the motor it is very smooth to me. My 14 tooth sprocket on the j shaft out put side was for a 415 chain . I ground it down narrower to fit a BMX chain figured it would where in, but it sticks a little other than that overall very cool!

I used a 7 speed twist click shifter on the 9 speed cog works great. Thats all the gears it needs is the bigger rear cogs. Don't even have to peddle assist this thing off the line ether. My only regret is the bike is a little heavy. Yet the Morini dos not mind at all! Just makes it a smoother ride..

I will look into mag wheels for it later. Then I can run it hard. Probably carry a spare rear chain at that point. I expect the price of having the luxury of this gearing will be a new last rear chain every 2000 miles unless I really get on it.

Thanks Fair I did get about 50 miles on this thing before it snowed outside. That was a bummer. I ground down the 14 tooth sprocket a little more. That made it perfect. Off the line it feels a bit like a china but the way I geared it I get to play with the RPMs on the Morini a little.

When this thing gets past about 3000 RPMs a howling noise like something from Steven King The Langolears movie begins to happen. It acts just like a turbo charged engine if you keep it full throttle! Kinda sounds like one spooling up! The bike pulls really hard and shows no hope of slowing down. I had to check the bike seat for teeth marks. More than once!

Now all that said I don't go around red lining it. I drive it for the most part just a tad harder than I did the china with the J shaft kit. Oh man If I want it theres a ton of power there!

I will make a you tube showing the way the suspension looks when one of my freinds helps me with the video!

Awesome build, great idea using the suspension pivot as youre jackshaft mounting point as well.

Well time to do some fessing up. I sad I would tell how this thing worked out so far. The rear Drive shaft sprocket from the jshaft the cobbled sprockets off the secondary chain. The one where I cut and rounded the crank arm off at the pivot point.

Where do I start? Its road worthy and currently working but not right First off the black sprocket was meant to go forward by peddling. Not by driven. {shape of the cog teeth} Now because the chain covers many teeth I doubt it will ever slip.

However Theres yet one more thing . This turned out to be the only 10,000 to 12,000 fear factor. Because the said sprocket was also Designed for shifting derailment. It is not perfectly round . Meaning that at high Rpms in the range I am saying at 5.8 HP , takes checking it over for anything loose before a wide open run. The chain will whip and surge the bike.

I can suspect I would never had noticed this phenomenon with a lower power RPM china. It is easily correctable with a steel sprocket from SBP. Little grinding And welding no prob. All that said I am not in a hurry to correct it as I stated in the beginning of my build I wanted a smooth 35 mile an hour bike. I met that goal!! Still gonna fix it though.

The said 7 speed click shifter is a joke I need a true 9. It seemed on day one I slapped it on to ride it was simply time to at that point. It did not get me into any trouble . The first day because luck of the aliment matched the gears I was skipping. Just does not work with the spread of the rear cog.

Over all I am very happy with this creation and thought I should fill in the blanks. No good reason for some poor chap to repeat my mistakes. My INTERNET connection is down {wallet} but shall have a you tube regardless in a very few days. God Bless..



This remark is for days gone by. My clutch was wrong slipping and since has been corrected. The chain whip is no longer an issue.

GH im amazed at all the work you did to get a morini on a homebuilt full suspension bike, excellent work. After it breaks in, let us know if you have chain problems with the rear deraileur and cassette... When I had a jackshaft on my modded china, I would snap sram 9 speed chains left and right, only getting 300 miles out of them at most. I would also have chain whip and perhaps that is what led to the chain failure... But that is one **** of a jackshaft kit and appears quite strong. Good Luck -Justin
