Project 300 "this is not sparta"

[razor02097]

An update... I have put about 1060 miles on her so far. The fiberglass packing that came in the emgo mufflers is no more....it all either burnt or rotted away. I'm pretty sure the packing that came with them isn't great quality and there wasn't much of it. I'm going to try repacking the mufflers if it isn't going to quiet it down enough I may be looking for other options.

I can't stand the noise level. Suggestions are welcome.

I am averaging 55-59 mpg I would like to improve it to over 60mpg. So far I have reduced weight but taking off the luggage rack and cleaning out pockets, backpack and tank bag and have done the typical things like tire pressure and tune up.
I think a big killer of MPG is the highway riding...Early testing revealed 100% throttle = 80MPH top speed, typical highway speeds are 65-70MPH...which I assume means I'm heavy on the throttle to get to those speeds. If that is just the nature of the beast I can accept that but if anyone has other suggestions for improving MPG I would welcome them.

Glad to hear she's running well!

One thing though is that losing the packing in the mufflers will probably make it breathe a little easier.. and therefore she might be running lean. I'd suggest repacking ASAP so you don't hole a piston or something drastic.

As far as MPG goes, yes, you'll need to find the "sweet spot" where she's most economical, probably around 5 - 6K RPM's is my guess, and whatever speed that puts you at is probably the most economical cruising speed.

Gearing can affect that too... oh, and wind resistance rather than weight at speed will have a bigger affect.

Well tonight I did repack the mufflers and it made all the difference! I've been keeping an eye on spark plugs to make sure there isn't signs of running lean. I'm still using the stock air box and filter also. Last time I checked the plugs they were a tan color.

I also installed one of these.... maier windshield. Interestingly enough that netted me about 3 more MPH on the shake down run today. I didn't install it for top speed though... its so I can ride more....heh...

Good stuff, glad to hear it

Yes, that screen should definitely make a difference.

I made my little fly screen to get some buffetting off me at speed and it works really well. I find though that I had to tilt it to be more vertical as it was original streaming the wind directly onto my chest which made it worse.

Pulled the plugs today... what do you think? Plug 1 on left plug 2 on right.

I'm crap at reading plugs but they look ok to me...

can u post a video of the pipes when you get them repacked? This bike looks awesome!!

I think I have a carb issue again... All of a sudden she is cold blooded and runs like s*** bogging, hesitating, popping...FML... I took the plugs to a trusted friend and he said they look okay. "Clean em up and put them back in." The plugs have just over 1000 miles on them. Since I know a monkey worked on them before I'm going to go ahead and replace a few things like the jets... Usually a soak and compressed air cleans the jets but monkeys tend to stick metal objects in there to poke out crud.

A side note... the low beam on the headlight burnt out. I bought a replacement which promptly blew out the low beam then the high beam when I switched to it. I put the old light back in and am using the high beam... WTF... I'm going back to the store to exchange it. I may pick up a battery also since I have no idea what condition it's in and don't know the age... it seems like all this s*** just started to happen...both the running issue and headlight could be related... maybe.

Thanks man, a buddy said the same thing. I think the jets are okay.

When i get her up and running I will

 

[basketcase]

its possibly overcharging, definatly something to look into asap.

 

[razor02097]

I'll have to check to see what the output is.

I'm in the process of breaking down the carbs... I need help... most tutorials have a filler tube with o rings. Mine doesn't have that....

The OEM part isn't available anymore and the seals seem to be molded on the tube.

Mate that looks just like the one on my 450.

Go to www.alphasports.com and find the part number on the fiche, then use their parts lookup tool to see what other models it's used on.

I got mine from Boulevard Suzuki as it was still available.

Alternatively, go to an auto store as they may have a fuel T piece that has the same dimensions on it.

When I redid my carbs I also had a similar fuel "t". I just reinstalled the part. No leaks.

Thanks man i did check with The part is 13685-11400 #57 on the fishe

I checked with a few dealers around as well as some online stores. I also checked boulevard Suzuki but none have it.... I guess I will have to reuse the part. The rubber is still supple so I hope it is okay.

 

[surviverguy]

I think it'll be ok. There's basically no fuel pressure. If it turns out that it does leak- you can always try plan B or plan C...

 

[Guest]

Yeah I only replaced mine because the first time I put fuel in it started to leak out of one side... if there's no leak and it seals, just leave it be.

 

[razor02097]

Okay so I ordered some things.

• Fuel line
• Fuel line spring (mine is bent up)
• Fuel line clips
• Vacuum line that goes to the fuel cock
• new springs for the slides (measured one .24" shorter than the other)
• new main and idle jets
• cycleorings o ring kit for CV carbs as well as the o rings for the intake boots

I dipped the carbs and started reassembling them as much as I could without the new parts.

I washed the hell out of the airbox using dish soap since I think that was part of the issue...see when I first got the bike the air filter wasn't exactly all there. It disintegrated. I'm thinking there was still some crud in the airbox.

The airbox and intake boots are still supple so I'm going to keep them.

I found a possible bad connection in the main fuse... I'm thinking about replacing the whole thing with an ATO fuse holder.

The battery tested good so I'm going to keep it.



On a side note... part 52 (13281-11400) in the picture is called a "net" Anyone know what it is for? I'm going to put it back in and all but I'm curious what it does?

This is what I'm talking about...
