Project 300 "this is not sparta"

[razor02097]

Well if you ever have ignition problems Pete can help you out. He just helped me with fitting a Dynatek S into mine.

I'm originally a Buckeye!

Cool man were you northern or southern Ohio? I recently came back to the forum. I took a break for a while but I am working on the project again. I read through your thread, it's nice to see someone do something other than what the factory had.

And don't forget Mekanix! I didn't realise you could stick the 250's mechanical advance onto the 300's... makes it real easy now that we know

[hjacobmiller]

Of course. Mechanix was the key!

I grew up in Piqua.

There's a ton of those fuel 'tees' on ebay right now.

When cleaning the carbs - watch for the tiny bearings under the choke lever. And also for the two tiny o-rings and washers underneath each fuel/air screw. I almost missed them my first time through the carbs.

[razor02097]

Yeah the manual mentioned the bearings man they are tiny!

I got it all back together minus new jets and cv slide springs. The float level I set at 21.4mm +/-1mm per the manual.

[razor02097]

Parts... many parts hooray for SGP!


Top going left to right... fuel hose, vacuum hose, hose spring. Bottom left to right... fuel hose clips, cv slide springs, 17.5 idle jets, 115 main jets.

Putting on more shiny




Here are the cv springs the old on top the new on bottom. I don't know if it will make much difference but the new springs are notably stiffer...



Carbs back together finally!





Now I need to get them back on...

Nice work!

I gotta say one of the fun things during my rebuild was getting a box from Boulevard in the mail, opening it, and see those red and white SGP labels...

[hjacobmiller]

Nice!

I wanted to ask you where you set your idle? I am having a hard time getting mine at the right spot.

[razor02097]

The manual says to set it at 1250 RPM but it's all by ear since I don't have a tach...so I try to guess where it should be.

Carburetors are back on!

Well last night I installed the boots to the engine with new O rings and hex bolts. Re installed the carburetors and put it all back together. 300 fired right up and the engine liked the mixture screws out 2 turns.

I ended up seeking another type of muffler. The fiberglass packed mufflers flow great and do a good job muffling the high pitch sounds but the lower pitch notes from the engine seem to be unimpeded... It is enough to give me a headache riding on the freeway for any length of time. I found the emgo reverse cone dunstall style mufflers that have metal baffles. The sound is much different. The high notes are muffled and the bass notes only come through at idle. Makes 300 sound like an older Japanese motorcycle (which it is )

Here is what it looks like. I haven't taken pictures with them on the bike yet maybe after work today...



Idling has a deep bass tone and a slight "puff puff" sound. Revving in neutral gives a metallic growl. On the road the sound is smooth with the same metallic growl. On the freeway the wind noise over powers the exhaust sound which is exactly what I wanted. I still have to replace the main fuse with an ATO style. I will probably stop after work and pick up a waterproof holder and fuse.

Nice! Where did you pick up the new ones up so quickly?

lapse in memory... I was thinking of another order... I remember now... I saw them on Amazon and looked up the seller. They are actually about $10 each cheaper on their site.

Regular shipping is like 9 bucks you can get one day for $38 if you are really impatient.

Ha I am really impatient. But not $38 impatient.

Did you get the 450 combo from cycle-orings?

[razor02097]

No I bought the 30mm O rings and the BS carb kit.

Just double up so you have it next time. Nice!

Did you check Z1 for your fuel T?
