REVIEW 4 cycle up and running report "IT RUNS"

[thatsdax]

ok. All finished..Except for Kill switch and another Kick stand. Forgive the shotty nature of the bicycle. It is a good bike though. TREK 800. So..Here is the deal so far with this new 4 Stroke.

As you can read in another post, Parts were missing. The sprocket that comes with the kit must be a 55T or larger. Since parts were missing, I put on a standard 44T. Later ....Checking the Blue tool bag that came with the kit, I found more than tools...There were all the missing parts I needed..O well...I should have checked the little blue bag..Who would have thought.........But..Anyway..Got her all installed with a 44T. Next...Was to start her and ride her and put some testing miles on this 4 stroke.....


Before starting...I pulled the plug and checked for spark. Standard operating procedure...SOP. On the first pull looking for spark, A double hand full of oil came flying out of the spark plug hole and went all over my garage wall...After some wiping...I covered the engine with a rag and pulled several more times blowing even more oil out from on top of the piston and a lot out of the exhaust port. WOW !! All that oil in the top of the cylinder may have seized my motor or even bent the connection rod with all that excess pressure. Maybe it would have broken my rope starter and saved the engine...Never less..It did not happen..Only because I wanted to check for spark by removing the plug. Since the engine is shipped with no crankcase oil, that must have just been a ton of assembly oil. A TON !!! so...I filled the tank with premix..Since that is all I have..And took the bike out to the drive way...No Joy..I pulled and pulled and pulled !!!! I hate Pull starts !!!!! Finally..I go some ether and sprayed some into the intake...She fired..only until the ether burned off.. I pulled the plug and dripped some fuel in there... Pulled several times...She fired..and ran till that burned off. So..Back into the garage she went... I pulled the carb and took it apart and cleaned all the jets. Oh..Did I mention..I filled the crankcase with 10W40 Valvoline.


ok...Back out to the drive way... All is ready except the kill switch..Pull...and pull..and..Did I mention I hate pull starts ? I hate pull starts...On the 3 pull..She lit.. I made some carb adjustments...And Jumped on the bike..And away I rode !!!!! Yea !!!!!!!!!!!!!!!!



Ok...We are cooking now !!! She runs great !!! About the same power and speed as the two stroke. This surprised me. It feels like more torque for sure..About the same speed...Not sure..But at any rate..She runs great with less vibration and less engine noise..But the auto clutch with reduction gear drive makes a whine !! I mean..A whine !! IT is louder than the the 2 stroke for sure !!! All because of this Transmission. Wow !!! It is a Whining Screamer !!! I thought that since this transmission is enclosed, and having no directions at all. I felt that this was a wet clutch and gear enclosure and that is was screaming for oil !!!! So..I took her home and added 1/2 pint of 10W40 to the enclosure ... And...That was a messy mistake. It all came back out the little vent hole drilled in the filler bolt . It came out ...All of it..All over my bike , leg and everything..So..I guess it is a dry clutch with reduction gear..lol...Anyway..That is the latest.
I will now go and put on miles and see if she goes or blows !!! That is why I bought this motor.. To test and see if they are better than the traditional 2 strokes. Well..Here are the pictures of one of the first installed and running 4 stroke kits I know of...I will keep you all posted of the progress !!! Thanks again... and remember.... Thats DAX !!!!!

please, guys, do continue...i'm on the edge of my seat. i almost chose to starve next month to buy onna those, but thought better of it...i really like food

ANOTHER UPDATE ON THE 4 CYCLE

The engine is identical to the GXH50 Honda. It may be a Honda. anyway.....I put on a 36T sprocket. It still pulls nice thanks to the good torque and speed is better for sure. Fast enough for a bicycle. I am guessing 40mph or so top speed. The engine is large still and wide. Vibrates but is not objectionable. My biggest complaint other than physical size is the Transmission Clatter and whine !!! It is embarrassing !!!! It is so loud !!! It is a shame too. Because..I want to hear the sound of the 4 stroke engine . I love the sound of thumpers. I also love the sound and snap of a 2 stroke. But..This is a thumper !! And I want to hear it...But the tranny is so dog gone loud !!! It clatters and whines so loud I can not hear my Engine!! This is something that has to be fixed. Under load the tranny is really really loud with the Auto Clutch clatter and the gear whine. It is aweful for sure. When you are not under full load..Then..It is no too bad..But still there ...O well.I am working on a fix..I will keep you all posted...

Hey Butch Or Any Other Honda Gxh50 Lovers/haters Can You Tell Us More About The Installation Your Bike Looks Nice.? Please

I Doing The Same Combo But Making Some Serious Modifications.
Eg Where And How To Install Kill Switch,

And Carb Tweeking And Break In

My Modifications Whatchathink?

Im Also Running A Wet Clutch But My Gearbox Is Vertical As Im Mounting It On The Rear Better All Around (lighter, Less Parts, Keep All My 28 Gears)

Also My Engine Came With A Muffeler Atached Can I Use This One?

Using Disk Break Hub To Attach Sprocket.

Mounting Gas Tank Above Engine. They Dont Call Me Fireball Jones For Nothing

And Using Some Racer Handel Bar As Have Gear Ajusters In The Ends Of The Handel Bar Like A Jet Fighter Stick.

Instead of jumping someone else's thread with your questions, maybe you could start your own thread
oh yeah, maybe introduce yourself and get aquainted as well

Wey To Put My Foot In My Mouth....sorry Dude For Highjacking The Thread. I Started My Own Thread Now.. I Think. Thanks

 

[rcjunkie]

So, does anybody know if the loud and annoying tranny whine issue has been fixed?

 

[gone_fishin]

don't mean to distract, but since you've finally revived this...i think someone has to think "inside the box" here...why all the gear-schtuff & complicatedness?

a simple torque convertor (off the shelf parts, for real) or a centrifugal to jackshaft arrangement (also available parts-wise) is all we need to get this "4-stroke happy-time" party started. both ideas are easily put into production and affordable to the consumer. i ran the real mini-bikes when i was a kid, i LOVE pull-starts, & a tuned 4-stroke starts every time.

seems to me the total cost of a kit (w/o engine) could ultimately be reduced by about 30% if we
apply a little of the ingenuity this country used to be respected for

i agree a 4 stoke happy time would be great!
