Title: the lc and the lightweight
Post by: m in sc on November 07, 2019, 01:18:16 PM
had these up elsewhere.  from end of October, swapping out the lightweight for the LC at work.

its nice when you can let a project bike sit for a month or 2, starts on 2nd kick and you can just ride it off, these both are like that.  :haw:

Nice duo! Add a red stripe on that LC and you'll gain 2 HP...  ;D :metal:

ACTUALLY.. i had soem BIG bodywork on it at one point with a tz stripe.

(legit gus kuhn tank and a Norton tail. it was HUGE) was a love/hate thing. When the tank started delaminating even after coating it, i relined it and sold it with full disclosure. Then i bought the benelli tank, its a real one, way before they got super popular.

Not sure I've ever seen the LC, so cool! The "lightweight" is one of my favorite real world rider bikes. :drool:

If you could only keep one, which would it be?

Awesome looking LC!  Very nice work.  Have not seen many major mods I have liked as they usually use the original tank which looks out of place at times.  This looks great!

thanks. they are both riders for sure, i do like them both.

The lc got complicated and fussy over the years, i do like it a lot though. I've actually detuned it a bit as it was very aggressive tune wise for a while. The lightweight was approached in the exact opposite direction being simple and light.

As far as which one i would keep if i had to choose between the 2? Probably the LC as i have had it forever in may different incarnations. and its a bit more user friendly overall.

Before I ask a dozen questions, are there already build threads for those amazing bikes which I can read?

I hate to ask a guy to tell his story again, but is the lightweight an Elsie frame and swinger with an R5 or RD engine?
Is the LC an RD frame and bottom end with Elsie top end and TZ water pump?
That's a nice wide rim on the back of the LC...what has been your experience regarding the effect that wide rim and rubber has had on handling?
I'm sure the answers to those will generate 9 more.
Thanks, Wade

No, its a 4130 foale style frame built by 27 cycles (danny). he and i worked on the layout and he fabbed it up almost 5 years ago. Its stock rd dimensionally and can use 'stock' location parts such as pipes and rearsets. he made 4 total, thats #1.  he has one, and 2 were sold.

(http://www.2strokeworld.net/wp-content/uploads/lightweight-rd/featherlight-frame-arm_10_zpsiwylsnoy.jpg)

motor is rd350, ported. RPRD webco heads. its 243 lbs wet.

Yes, exactly.

That's a nice wide rim on the back of the LC...what has been your experience regarding the effect that wide rim and rubber has had on handling?

it has been good.  the front is wide as well, but the rims vs tires are correct to each other. However any weight saved by going to spoked rims (it had cast wheels) were lost with the weight of the rubber. IF i were to do it over, id go just 1 size smaller. the chain is VERY close to the tire and required offset sprockets ft and rear. But it handles really well overall.

Thank you. I have an RD in line to become a project, and one possible scenario is fitting an Elsie swinger and shock, which looks difficult but possible. I also want spoked wheels but am wary of going too wide, as I've read a couple of people to opine that wide wheels adversely affect ( they said ruin) the handling of these bikes (now that I've fitted wider 17s to the project 1st in line, an RZ). I have a 130 on an FZ wheel on the rear of my daily rider RZ, and it has always felt fine...but a brief stint with a 120 on the front made it turn in like a '70 F250 on bias-plies. No wider than a 110, please.
How did you choose the Elsie top end on the AC bottom? Advantages vs. using an entire Elsie engine?
Thanks again for your time!

actually, the LC arm bolts in (but the large slot is swapped). however, the length of the shock mount will limit your options on shocks. I designed the geometry on the rd arm to accept a common shock, in my case, cbr1000rr shock. so, its 'shorter'. Or, you would have to run an 35 year old LC shock or equivalent, at the time i couldn't find anything.. I had an lc swinger and test fit it and did the math but wasn't worth it. this is the 3rd bike i've done that setup on, and you can use a cbr600rr shock as well, but the dimensions of the shock support are a bit different. i -think- it was 7 5/8 for the 1000 shock and 8" or so for the cbr600 shock, but i would have to check my notes.  just to be aware, theres zero weigh savings going mono, but the arm is stronger and it does handle better. also, on my lightweight in particular, the bike was so light, i had to swap out the sp[ring to a 650 ninja one, was a brick with a stock cbr shock.

well, that depends on the rim width again. the ONLY way i would run wider tires is to have the correct wheel. a 120 on a stock rz front rim is bad. I used to run 110 and 90 on the rz, felt great, i'm a firm believer in the right sized tire for the rim.. note the lightweight is sporting small stock wheel sizes. HOWEVER, the lc does not handle slow at all, of course it has an fzr400 rear swinger and a set of works shocks that were made for that bike. Also, there's a worked FZR/Fazer front end on it.  I mean, look at a ninja 250, they have wide wheels and handle like a rail.

Thanks again for your time!

the whole reason that project even happened was back in '04 i got my hands on a set of lc jugs and began experimenting. it just got way out of hand. ac bottom end advantage? none except at the time it was what i had and was a direct bolt in. Ive done 2 of those, they work well. the other one i did used an electric pump and retained the oil injection system.  LC bottom end makes more sense as it comes with a cdi and the water pump and oil pump already, but you have to redo the motor mounts, not a big deal. But my way is if nothing else, more interesting to look at, but def NOT superior technically :twocents:

My front brake is coming together; cleaned up my Brembo calipers, have rebuild parts and an Aprilia RS125 master cylinder on the way. I have two calipers, two discs and lugs on both stanchions, so I can put the disc on either side of the wheel. Most OEM single street bike discs seem to be on the right, while most dirt bikes have them on the left as Mark has done. Any reasoning behind the left or right fitment?

good question. TBH, cosmetic. to balance out the rear disc visually. thats it.  :dawg:
