Default Re: what did you do to your motor bike today?

I battled with two things during the major heat wave here. Fuel petcock did not have enough steady flow for sustained red line ''the rubber inerds warped'' and I had to place the the fuel line into a cooler spot. In the end with that carby I had taken the petcock out and ran the line straight back with a inline filter of coarse. The float was working fine.

What I always had was if I sustained a somber Idle for way too long without periodically bumping the throttle just had to raise it a little '' note did not have to rap it'' I had to go half a neighborhood block to blow the motor out. Then it ran great perfect!

The Morini has been a way different animal than a H.T. At 11,000 12,000 rpm as compared to a 6000 rpm motor. Think of a hot rod V8 motor with a lot of carb loading up from excessive Idling is the best description I got like when its at a mechanic shop and got moved and parked for a week and never blew out.

I am at 6000 feet above sea level I did just about absolutely everything with that original carb set up. I am convinced it was as good as it gets. Went three Atomizers leaner among trying jetting and it was not bad after that!

I spent a small fortune in jets etc and everything for these model Del's fits another Del! So I am ready for a custom bigger jug piston set later on and or to go to one of our bike races at a different altitude.

I love Del's now!!

6000 foot would be about roughly a 30% percent difference in Horse power from sea level so I hear and after studying jetting through other forums across the country the info reflects this percentage wise in jet sizing for every 1000 foot.

Also reading about Ultra Light planes you get this info too.

I got one of Nidyanazo's old carbs his was selling he kept from a custom Morini he sold. The Del 21mm I put on today. Thanks buddy! Now I know what he jetted that carby at at sea level

I can't always say I know what I am doing. Always learning something new that's what I love about this hobby!!

The 21 is a improvement with the extra high elevation thin air here. Its kinda like a touch of porting just breaths much better. It is essentially the exact same carb just a larger opening at the intake side. The kinda feel you get when you port out a china 2 smoke kinda thing for the first time. I pack more into the motor now. Plus since I used the original custom jets I should in theory get a tad better gas mileage. lol.

Default Re: what did you do to your motor bike today?

I spent 4 days playing with my throttle cable, which is too long. I tried securing it so that it does not stick out to far, yet free enough so when I turn my handle bars the bike doesn't reve or idle high. Finally concluded to cut the d@mn thing.

Before I did it, my dad comes a long, and secures it so that it doesn't stick out, yet moves freely so the bike doesn't reve or idle high when the handlebars are turned.

I see how he did it. Why I didn't thing of it during my 4 days of playing with the throttle, I have no clue... :/

I am loving the new Delorto SLA clone carb I got from PB... It is a darn sight better than any of the stock carbs...

Worked on my chain tensioner today, the nylon roller striped so it was time to get creative. Used a sprocket from a derailer, and lots of washers.

Does anyone know if hardware store sell nylon washers or not? Don't mind the metal, but nylon would be more chain friendly I think.

Dads are always smarter or just see the obvious easier... at least mine was and I hope I live up to that model with my kiddos..

I believe my Project Scooterguy w/Tanaka 47R engine is done.

Today I rejuvenated a build I started last year.....Project 29er. This time, it'll be with TWO 4.5 hp CY460 engines on a Staton dual-engine gearbox and NuVinci hub.

I'll keep you all posted.

I botched the re-jet job on my cns yesterday.
Soldered it and drilled to #74.

Attempted to use 3 rings cit from 3/4 copper waterpipe to replace the pvc manifold spacer the cns uses. I've got the thinner grade of copper tube, (I never could remember which is which, type L or type M), but 3 rings is still too thin.

and I made em 14mm long and that's NOT good because it bumps the weld on the stock manifold and does not allow the cns to seal up against it's manifold washer/seal.

Changed out the petcock on the peanut tank! This one taken off one of my HF generators is much more positive and does not leak.

...first thing when I turned it on is the cns float valve stuck open and dumped gas all over $#@!

and I got the float adjust level now.
Anyone got any tips or hints to get the float and needle valve working properly!

Really jealous of GH with his great explanation of adjusting his new dellorto!!!
Gosh I'd like to have one of those!

Back to the drawing board! I wanted to ride today...

Haven't had the happy time out for a while, so I greased up the clutch actuator and the gears. Pinched my finger when I was applying the grease and moved the tire too soon. Ouch, drew blood and bled for a while. Note to self, apply grease with screwdriver from now on.

Filled tank. Wanted to use up rest of gas so's I could try out the opti 2. Filled tank too far. When shook gas spewed out of gas cap and ran down tank and dripped all over motor. Removed banjo fitting and drained excess gas out of tank. Note to self, do not fill tank over 3/4 full.

Rode bike to grocery store and bought groceries and sandwich for lunch. Noticed that bike rides rougher, stinks and is much louder than the nice 4 stroke that is the reason I haven't been riding the happy time much anymore. Note to self, to avoid further injuries and possibility of burning self to a crisp when gas leaks out of tank and onto running hot motor, get rid of happy time ASAP.

Sounds to me like you didnt have a very "happy time"........lol!

From what I see here.......just about every bad experience you just described here could have been avoided by not doing the things you said you shouldn't have done and already having that china girl tuned in and running on the Opti2..... dont give up on her before she has a chance to have a good fuel mix in her belly, she be much nicer to ya then, virtually NO smkoe and very little smell and more power to boot.....!

Sorry.... just had to rib you and encourage you a bit at the same time.....!

Peace, map
